DETAILED DESCRIPTION OF THE INVENTION

[0020] Some configurations of the systems and methods disclosed herein may involve a multi-band, aperture-sharing, interleaved antenna array. The antenna may be a structure for transmitting and / or receiving electromagnetic signals. The antenna array may be an antenna including multiple elements, where each element may be capable of emitting and / or receiving electromagnetic (e.g., RF) signals. The elements may include one or more metallic structures for emitting and / or receiving electromagnetic signals. In some examples, the elements may be implemented as and / or included in a printed circuit board (PCB) or otherwise disposed on or in a substrate.

[0021] Some configurations of the systems and methods disclosed herein may involve antenna arrays and / or antennas for signaling in the 20-300 gigahertz (GHz) frequency range (e.g., millimeter wave (mmWave) signaling in the 30-300 GHz frequency range and / or other frequency ranges). For example, some configurations of the systems and methods disclosed herein may involve one or more implementations of a multi-band aperture-sharing interleaved mmWave antenna array.

[0022] Some example antennas described herein may signal within frequency ranges (e.g., bands) utilized for fifth-generation (5G) or new radio (NR) communications, fourth-generation (4G) communications, long-term evolution (LTE) communications, third-generation (3G) communications, evolved Universal Mobile Telecommunications Service (UMTS) communications, Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) communications, Bluetooth communications, and the like.

[0023] In some examples, an antenna (e.g., an mmWave antenna module for 5G) may be integrated within a wireless device such as a cell phone. For example, a cell phone may be implemented to include multiple antennas to provide coverage in all directions. It may be beneficial to improve the coverage and / or radiation performance of the antenna from within a limited volume (e.g., the volume occupied by the antenna within the device).

[0024] As more signaling bands become available, it may be beneficial to support (e.g., provide communication signaling for) more signaling bands. For example, it may be beneficial for, for example, an antenna to support one or more new bands (in addition to legacy bands).

[0025] Some examples of the techniques disclosed herein may provide interleaved antenna arrays with improved performance and / or coverage. Some examples may enable supporting more bands without increasing the physical size of the antenna array. Some examples of antenna arrays described herein may have a maximum dimension of 30 millimeters (mm) or less. For example, some of the antenna arrays described herein may have widths of 27.2 mm, 26.2 mm, 25 mm, or another width of 30 mm or less. Some examples of antenna arrays described herein may have a length dimension of 4 mm or less (e.g., 3.5 mm). In some examples, the antenna array may be between 0.5 mm and 1.5 mm in height. In some examples, the antenna element PCB may be 0.94 mm in height. Some examples may provide an antenna array that supports the 47.2 to 48.2 GHz band (sometimes referred to as the 48G band or n262 band) along with one or more other bands (e.g., the 26.5 to 29.5 GHz (n257) band, the 24.25 to 27.5 GHz (n258) band, the 27.5 to 28.35 GHz (n261) band, the 37 to 40 GHz (n260) band, and / or the 39.5 to 43.5 GHz (n259) band).

[0026] The element size and element spacing are factors for a multiband antenna array. A multiband antenna array may be an antenna that supports multiple bands. In some examples, a multiband antenna array may support multiple bands by including an element that supports a single band and another element that supports another single band. A multiband element may be an element that supports multiple bands. For example, a multiband element itself may be utilized to transmit and / or receive on multiple bands. A single-polarized element may be an element that supports a single polarization (e.g., vertical polarization, horizontal polarization, or polarization along only one direction, etc.). A dual-polarized element may be an element that supports two polarizations (e.g., vertical polarization and horizontal polarization, polarization along two directions, tilt polarization, ±45-degree polarization, etc.).

[0027] An example of a multi-band antenna array may be an antenna array with multi-band, dual-polarized elements spaced at regular intervals. In this example, all supported bands share the same elements (sometimes called aperture sharing). Having the same spacing for all elements may lead to reduced scanning performance for higher bands if the elements are spaced too far apart, or may lead to increased coupling between elements for lower bands if the elements are spaced too closely together.

[0028] An example of a multiband antenna array may be an antenna array having interleaved multiband and dual-polarized elements, where each type of element may exclusively support a band or set of bands. For example, multiple elements of a first type may be interleaved with multiple elements of a second type, with each type of element exclusively supporting a band or set of bands (e.g., without aperture sharing). This example of a multiband antenna array may result in a relatively large physical array and poor scanning performance in the relatively high bands. For example, the spacing between elements may be too large for the relatively high bands, which may create grating lobes. In some examples, "interleaving" may mean interleaving elements of different types, where one (e.g., only one) element of one type may be disposed between two elements of another type (e.g., in the case of a series of at least three elements). For example, element type A may be interleaved with another element type B when arranged in at least an alternating pattern ABA. In some examples, "interleaving" may mean alternating elements, where one or more elements of one type may be disposed between two elements of another type (e.g., ABBA). In some examples, the elements of an antenna may be disposed only along rows (e.g., only along lines or rows, without being disposed along another dimension or "column").

[0029] An example of an antenna array may be a dual-band single-polarized array. Different spacing of elements for the lower dual band and for the higher band may improve scanning performance. However, the element placement in this example may increase the array size and / or may not allow for dual polarization.

[0030] Another example of an antenna array may be a multi-band interlaced array, in which a single-band array may be interlaced with multi-band elements where elements of different arrays occupy the same space at the same time.

[0031] Various configurations are now described with reference to the Figures, where like reference numbers may indicate functionally similar elements. The systems and methods as generally described herein and illustrated in the Figures could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of several configurations, as represented in the Figures, is not intended to limit scope, but is merely representative of the systems and methods, as claimed.

[0032] FIG. 1A illustrates a top view of an example antenna 102 according to some of the configurations described herein. FIG. 1B illustrates an elevation view of the antenna 102 of FIG. 1A. FIGS. 1A and 1B are described together. In this example, aspects (e.g., dimensions, physical relationships, etc.) may be described with respect to the x-axis, y-axis, and / or z-axis. In some examples, "width" may refer to the x-axis, "length" may refer to the y-axis, and "height" may refer to the z-axis. The antenna 102 may include a first plurality of first elements 104a-d and a second plurality of second elements 106a-c. In this example, four first elements 104a-d and three second elements 106a-c are illustrated. In other examples, other numbers of first elements 104a-d and / or second elements 106a-c may be implemented.

[0033] In some configurations of the antennas described herein, some elements may include one or more radiators. A radiator may be a metallic structure for transmitting and / or receiving electromagnetic signals. Examples of radiators include a patch (e.g., a substantially planar metallic structure), a strip, etc. In some examples, a radiator may be connected to one or more feeds. In some examples, one or more of the elements described herein (e.g., the first element, the second element, the third element, and / or the fourth element, etc.) may include a parasitic radiator. For example, one or more of the elements described herein may include a parasitic radiator disposed above (e.g., stacked above) a radiator connected to a feed. For example, a parasitic radiator may be a parasitic metallic patch disposed above a radiator connected to a feed or above multiple radiators connected to multiple feeds. A parasitic radiator may not be connected to a feed. In some examples, a parasitic radiator may increase bandwidth. In some examples, the parasitic radiator may be smaller in size than (or approximately the same size as) a radiator disposed below the parasitic radiator (e.g., a radiator connected to the feed).

[0034] In this example, each of the first elements 104a-d may include a respective first radiator 108a-d and second radiator 118a-d. For example, the first radiator A 108a of the first element A 104a may be a substantially planar structure, and the second radiator A 118a of the first element A 104a may be a substantially planar structure. The radiators may have similar or different sizes (e.g., dimensions). In some examples, one or more of the radiators described herein may have a λ radiator for one or more supported bands. g / 2 and λ g / 3, where λ gis the wavelength of the supported band in the dielectric substrate of the antenna. In some examples, one or more of the radiators described herein can function with a relatively large bandwidth (e.g., 6 GHz or greater) by disposing the patch farther away from ground (e.g., from the bottom of the element, from the base, etc.) and / or by stacking one or more parasitic radiators (e.g., patches). In the example of FIG. 1, the first radiator A 108a is larger in the x and y dimensions than the second radiator A 118a. In some configurations, one or more elements (e.g., first elements 104a-d) may include a stack of metallic patches. In this example, the first radiator A 108a is below (e.g., stacked with) the second radiator A 118a in the z dimension. For example, the first radiator A 108a and the second radiator A 118a may overlap in the x and y dimensions. In some configurations, a lower radiator (e.g., the first radiator A 108a) may include holes to allow feeds (e.g., the third feed A 112a and / or the fourth feed A 116a) to pass through to an upper radiator (e.g., the second radiator A 118a). In some examples, each metallic patch may support a respective set of bands. For example, the first radiator A 108a and the second radiator A 118a may support a respective band and / or a respective set of bands (e.g., the first radiator A 108a may support a set of lower frequency bands, and the second radiator A 118a may support a set of higher frequency bands). In some examples, all bands supported by one or more of the antennas described herein may be greater than 23 GHz in frequency and / or may be in the mmWave frequency range. For example, all bands supported by the antenna 102 may be above 23 GHz in frequency and / or may be in the mmWave frequency range.

[0035] As used herein, the term "connect" and variations thereof may refer to a contacting electrical connection. As used herein, the term "couple" and variations thereof may refer to an electromagnetic coupling (e.g., a capacitive coupling and / or a non-contact coupling). In some examples, one or more of the feeds described herein may be direct feeds, in which the feed is connected to the radiator. In some examples, one or more of the feeds described herein may be coupling-fed, in which the feed is coupled to the radiator (e.g., capacitively coupled to the radiator and / or non-contacting with the radiator). In some examples, one or more of the feeds described herein may be slot-fed. Various feed structures may be implemented in the various examples of antennas described herein.

[0036] The first radiator A 108a may be connected and / or coupled to the first feed A 110a and the second feed A 114a. The second radiator A 118a may be connected and / or coupled to the third feed A 112a and the fourth feed A 116a. The first elements B-D 104b-d may each include a respective first radiator B-D 108b-d connected and / or coupled to a respective first feed B-D 110b-d and a respective second feed B-D 114b-d. The first elements B-D 104b-d may each include a respective second radiator B-D 118b-d connected and / or coupled to a respective third feed B-D 112b-d and a respective fourth feed B-D 116b-d. The feeds may be couplings (e.g., wires, connections, etc.) between a transceiver (e.g., a transmitter, a receiver, and / or a radio frequency integrated circuit (RFIC)) and the radiator. In some configurations, each feed may correspond to a polarization. For example, the first feed A 110a may correspond to one polarization (e.g., horizontal polarization, +45 degree polarization, etc.), and the second feed A 114a may correspond to another polarization (e.g., vertical polarization, −45 degree polarization, etc.) (e.g., for a first band or a first set of bands). The third feed A 112a may correspond to one polarization (e.g., vertical polarization, −45° polarization, etc.), and the fourth feed A 116a may correspond to another polarization (e.g., horizontal polarization, +45° polarization, etc.) (e.g., for a second band or a second set of bands). For example, some elements (e.g., first elements 104a-d) may each have four feeds with two polarizations. When an element is connected and / or coupled to feeds for two polarizations, the element may be dual-polarized. For example, each of the first elements 104a-d may be dual-polarized. In some examples, different elements may have opposing feed arrangements. For example, the first elements C-D 104c-d may have opposing (e.g., mirrored) feed arrangements compared to the first elements A-B 104a-b.

[0037] In the example of FIG. 1 , each of the first elements 104a-d includes four feeds. For example, two of the feeds may be utilized for a first set of bands (e.g., for transmitting and / or receiving on the first set of bands) and the other two of the feeds may be utilized for a second set of bands (e.g., for transmitting and / or receiving on the second set of bands). In some examples, one or more elements may include two feeds (e.g., one or more elements supporting multiple sets of bands may include only two feeds). For example, one or more of the first elements 104a-d may instead include only two feeds. Each of the two feeds may correspond to a different polarization, and / or signals on the first set of bands may be multiplexed with signals on the second set of bands for each of the polarizations.

[0038] In this example, each of the second elements 106a-c may include a respective radiator 120a-c. For example, the radiator A 120a of the second element A 106a may be a substantially planar structure. In this example, the radiator A 120a of the second element A 106a may be similar in size in the x and y dimensions to the second radiator A 118a of the first element A 104a. In some examples, the radiators in different elements may be at the same height or different heights in the z dimension. For example, the radiator A 120a of the second element A 106a may be at a different height than the first radiator A 108a and / or the second radiator A 118a of the first element A 104a.

[0039] The radiator A 120a may be connected and / or coupled to the first feed A 122a and the second feed A 124a of the second element A 106a. The second elements B-C 106b-c may each include a respective radiator B-C 120b-c connected and / or coupled to a respective first feed B-C 122b-c and a respective second feed B-C 124b-c. The first feed A 122a of the second element A 106a may correspond to one polarization (e.g., horizontal polarization, +45 degree polarization, etc.), and the second feed A 124a may correspond to another polarization (e.g., vertical polarization, −45 degree polarization, etc.) (e.g., for a second band or a second set of bands). For example, some elements (e.g., second elements 106a-c) may each have two feeds with two polarizations. In some examples, the antenna 102 array may have two polarizations (e.g., horizontal and vertical polarization, ±45 degree polarization, etc.). Each of the second elements 106a-c may be dual polarized. In some examples, different elements may have similar feed arrangements. For example, second elements A-C 106a-c may have similar feed arrangements.

[0040] In some examples, one or more elements may include a material. For example, one or more radiators of an element may be embedded in a material (e.g., a support material, a dielectric material, etc.). For example, the first element A 104a may include a first radiator A 108a and / or a second radiator A 118a embedded in a material (e.g., a support material and / or a dielectric material). In some examples, the material for each element (e.g., each of the first elements 104a-d and each of the second elements 106a-c) may be separate. For example, the material (e.g., the support material and / or the dielectric material) of the first element A 104a may be located remotely from the material (e.g., the support material and / or the dielectric material) of the second element A 106a. In some examples, each of the first elements 104a-d may be implemented as and / or included within a separate PCB.

[0041] The second elements 106a-c may be interleaved with the first elements 104a-d. For example, the first elements 104a-d may alternate with the second elements 106a-c along a dimension (e.g., the x-dimension) of the antenna array. In some configurations, one or more of the first elements 104a-d may have larger dimensions than one or more of the second elements 106a-c. For example, the first element A 104a may be larger in size in the x-dimension than the second element A 106a. In some examples, each of the second elements 106a-c may be implemented as and / or included within a separate PCB. In other examples, all of the elements of the antenna 102 may be included on or in a single PCB or substrate and / or packaged together in a module. Although not explicitly described below, in some implementations, other example antennas mentioned herein may be similarly configured.

[0042] In some configurations, each of the first elements 104a-d and the second elements 106a-c may be disposed on a base 126. The base 126 may be attached to (e.g., coupled to) and / or support the first elements 104a-d and the second elements 106a-c. In some examples, the base 126 may be a PCB. For example, the first elements 104a-d and the second elements 106a-c may be PCBs (e.g., individual PCBs, separate PCBs, etc.) assembled on the base (e.g., a larger PCB or other substrate). For example, one or more (e.g., PCBs) of the first elements 104a-d and / or second elements 106a-c may be soldered to (e.g., within) the base 126 (e.g., a larger PCB). In some configurations, one or more substrates of the first elements 104a-d, second elements 106a-c, and / or base 126 may be similar or different. In some examples, the substrate of the first elements 104a-d, second elements 106a-c, and / or base 126 may include one or more dielectric materials. In some configurations, one or more substrates may include a resin with a reinforcing material (e.g., fiberglass, paper, etc.). In some examples, the base 126 (e.g., PCB) may include one or more metal layers (with supporting and / or dielectric materials). In some configurations, the base 126 may transfer signals from one or more of the first elements 104a-d and / or second elements 106a-c to one or more transceivers (which may, for example, be located on the opposite side of the base 126 (e.g., PCB)). In some examples, each of the first elements 104a-d and / or second elements 106a-c may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 126 (e.g., a larger PCB). In some examples, the first elements 104a-d and / or second elements 106a-c may be implemented within a single PCB that is mounted within the base 126 (e.g., a larger PCB).In some examples, at least two of the PCBs of the elements (e.g., first elements 104a-d and second elements 106a-c) may be of different heights. In some examples, the antenna 102 array may be implemented in a single (e.g., monolithic) PCB. For example, all elements of the antennas described herein may be on the same PCB. In some examples, one or more of the bases described herein (e.g., base 126) may be an active PCB having an approximate height of 0.4 mm.

[0043] In some configurations, each of the first elements 104a-d may be configured to support a first set of bands and a second set of bands. Supporting one or more bands may mean that the element may be configured to transmit and / or receive one or more signals within the one or more bands. For example, one or more signals within a supported band may be provided and / or forwarded to an element supporting that band. For example, a transmitter may provide one or more signals within a band to one or more elements supporting that band via one or more corresponding feeds. Additionally or alternatively, one or more signals within a band received by an element supporting a band may be provided to a receiver via one or more corresponding feeds. In some examples, an element may support a band if the element meets one or more performance criteria (e.g., maximum return loss and / or minimum gain). For example, if an element provides a maximum return loss of -10 decibels (dB) or less and / or a minimum gain of 2 decibels (dBi) or more relative to an isotropic antenna, the element may support a band (e.g., n259, n260, n262, and / or bands higher than 29.5 GHz, etc.). In some examples, if an element provides a maximum return loss of -7.5 dB or less and / or a minimum gain of about 2 dBi or more, the element may support a band (e.g., bands between 24.25 and 29.5 GHz, n257, n258, and / or n261, etc.). While example performance criteria are given for elements, in some examples the antenna array gain may be significantly greater.

[0044] In some configurations, the second set of bands may be mutually exclusive with the first set of bands, e.g., none of the bands in the first set of bands may be included in the second set of bands, and / or none of the bands in the second set of bands may be included in the first set of bands.

[0045] In some configurations, each of the second elements 106a-c may be configured to support a second set of bands. For example, each of the second elements 106a-c may support the second set of bands that are also supported by the first elements 104a-d. In some examples, each of the second elements 106a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands).

[0046] In some configurations, the first set of bands are lower in frequency than the second set of bands, e.g., each band in the first set of bands may be in a lower frequency range than any band in the second set of bands.

[0047] In some configurations, the first element spacing for the first set of bands may be greater than the second element spacing for the second set of bands. For example, the first set of bands may be supported by the first elements 104a-d and not by the second set of elements 106a-c. Thus, the first element spacing for the first set of bands may be the distance between the center of the first element A 104a and the center of the first element B 104b. The second set of bands may be supported by each of the first elements 104a-d and the second elements 106a-c. Thus, the second element spacing for the second set of bands may be the distance between the center of the first element A 104a and the center of the second element A 106a.

[0048] Figure 2A illustrates a top view of a more detailed example of an antenna 202 according to some of the configurations described herein. Figure 2B illustrates an elevation view of the antenna 202 of Figure 2A. Figures 2A and 2B are described together. The antenna 202 and / or one or more components of the antenna 202 may be examples of corresponding components described with respect to Figures 1A and / or 1B. The antenna 202 shown in Figures 2A and 2B is an example of a multi-band dual-polarized shared-aperture interleaved antenna.

[0049] The antenna 202 may include a first plurality of first elements 204a-d and a second plurality of second elements 206a-c. In this example, four first elements 204a-d and three second elements 206a-c are shown.

[0050] In this example, each of the first elements 204a-d may include a respective first radiator 208a-d and second radiator 218a-d. In this example, the first radiator A 208a is larger than the second radiator A 218a in the x and y dimensions. In this example, the first radiator A 208a is below (e.g., stacked with) the second radiator A 218a in the z dimension. In some examples, one or more of the elements described herein may include one or more additional radiators. For example, the first element A 204a may include five additional radiators (e.g., four off-center rectangular radiators and a central rectangular radiator) on the top layer of the first element A 204a. For example, the parasitic radiator 215 may be a metallic patch of the first element A 204a.

[0051] The first radiator A 208a may be connected and / or coupled to the first feed A 210a and the second feed A 214a. The second radiator A 218a may be connected and / or coupled to the third feed A 212a and the fourth feed 216a. The first elements B-D 204b-d may each include a respective first radiator B-D 208b-d connected and / or coupled to a respective first feed B-D 210b-d and a respective second feed B-D 214b-d. The first elements B-D 204b-d may each include a respective second radiator B-D 218b-d connected and / or coupled to a respective third feed B-D 212b-d and a respective fourth feed B-D 216b-d. The first feed A 210a may correspond to a first polarization, and the second feed A 214a may correspond to a second polarization (e.g., for a first band or a first set of bands). The third feed A 212a may correspond to a second polarization, and the fourth feed A 216a may correspond to the first polarization (e.g., for a second band or a second set of bands). Each of the first elements 204a-d may be dual-polarized. In some examples, the first elements C-D 204c-d may have an opposed (e.g., mirrored) feed arrangement compared to the first elements A-B 204a-b.

[0052] In some examples (e.g., some examples described herein), the first polarization may be horizontal, vertical, +45 degree, −45 degree, or other polarization. In some examples, the second polarization may be vertical, horizontal, −45 degree, +45 degree, or other polarization. In some examples, the first polarization may be complementary to the second polarization (e.g., about 90 degree offset from the second polarization). In some examples, inter-band and / or inter-element polarization pairs (e.g., first and second polarizations) may be of the same type or different types (e.g., pairs) of polarization.

[0053] In this example, each of the second elements 206a-c may include a respective radiator 220a-c. In this example, the radiator A 220a of the second element A 206a may be similar in size in the x and y dimensions to the second radiator A 218a of the first element A 204a. The radiator A 220a of the second element A 206a may be at a different height than the first radiator A 208a and / or the second radiator A 218a of the first element A 204a. As discussed above, in some examples, one or more of the elements described herein may include one or more additional radiators. For example, the second element A 206a may include two radiators, including the radiator 217 on the top layer of the second element A 206a (e.g., centered above the radiator A 220a).

[0054] The radiator A 220a may be connected and / or coupled to the first feed A 222a and the second feed A 224a of the second element A 206a. The second elements B-C 206b-c may each include a respective radiator B-C 220b-c connected and / or coupled to a respective first feed B-C 222b-c and a respective second feed B-C 224b-c. The first feed A 222a of the second element A 206a may correspond to a first polarization, and the second feed A 224a may correspond to a second polarization (e.g., for a second band or a second set of bands). Each of the second elements 206a-c may be dual-polarized. The second elements A-C 206a-c may have similar feed arrangements.

[0055] The first element A 204a may include a first radiator A 208a and / or a second radiator A 218a embedded in a material (e.g., a support material and / or a dielectric material). The material (e.g., the support material and / or the dielectric material) of the first element A 204a may be located remotely from the material (e.g., the support material and / or the dielectric material) of the second element A 206a.

[0056] The second elements 206a-c may be interleaved with the first elements 204a-d. The first element A 204a may be larger in size in the x dimension than the second element A 206a.

[0057] Each of the first elements 204a-d and second elements 206a-c may be disposed on the base 226. In some examples, each of the first elements 204a-d and second elements 206a-c may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 226 (e.g., a larger PCB). In some examples, the first elements 204a-d and second elements 206a-c may be implemented within a single PCB that is mounted within the base 226 (e.g., a larger PCB). In some examples, the antenna 202 array may be implemented within a single (e.g., monolithic) PCB.

[0058] In some configurations, each of the first elements 204a-d may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 37-40 GHz band (e.g., n260), the 39.5-43.5 GHz band (e.g., n259), and / or the 47.2-48.2 GHz band (e.g., 48GHz band). In this example, the second set of bands may be mutually exclusive from the first set of bands. In this example, the first set of bands is lower in frequency than the second set of bands. In some of the examples described herein, the highest frequency in the first set of bands may be separated from the lowest frequency in the second set of bands by more than 6 GHz.

[0059] In some configurations, each of the second elements 206a-c may be configured to support a second set of bands. For example, each of the second elements 206a-c may support a second set of bands that are also supported by the first elements 204a-d. In some examples, each of the second elements 206a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands). In some examples, the number of elements for the first set of bands (e.g., four) may be fewer than the number of elements for the second set of bands (e.g., seven). For example, the antenna 202 may provide a 1 x 4 element array for the first set of bands and a 1 x 7 element array for the second set of bands.

[0060] In this example, the first element spacing 228 for the first set of bands (e.g., 6.4 millimeters (mm)) may be greater than the second element spacing 230 for the second set of bands (e.g., 3.2 mm). For example, the first set of bands may be supported by the first elements 204a-d and not by the second set of elements 206a-c. Thus, the first element spacing 228 for the first set of bands may be the distance between the center of the first element A 204a and the center of the first element B 204b. The second set of bands may be supported by each of the first elements 204a-d and the second elements 206a-c. Thus, the second element spacing 230 for the second set of bands may be the distance between the center of the first element A 204a and the center of the second element A 206a.

[0061] In this example, the first elements 204a-d (for the first set of bands and the second set of bands) and the second elements 206a-c (for the second set of bands) may support multiple bands through aperture sharing. The example of Figures 2A and 2B may provide one or more advantages. This example may include an increased number of elements (e.g., second elements 206a-c) dedicated to the second band to obtain increased gain and effective isotropic radiated power (EIRP) within the second set of bands. Different element spacing for the first set of bands and the second set of bands may provide improved scanning performance. This example may provide a potential avenue for use in various countries (e.g., globally) using the 48G band.

[0062] Figure 3 illustrates a top view of another example antenna 302 according to some of the configurations described herein. The antenna 302 and / or one or more components of the antenna 302 may be examples of corresponding components described with respect to Figures 1A and / or 1B. The antenna 302 illustrated in Figure 3 is an example of a multi-band dual-polarized shared-aperture interleaved antenna.

[0063] The antenna 302 may include a first plurality of first elements 304a-b, a second plurality of second elements 306a-c, and a third plurality of third elements 344a-b. In this example, two first elements 304a-b, three second elements 306a-c, and two third elements 344a-b are shown.

[0064] In this example, each of the first elements 304a-b may include a respective first radiator 308a-b and second radiator 318a-b. In this example, the first radiator A 308a is larger than the second radiator A 318a in the x and y dimensions. In this example, the first radiator A 308a is below (e.g., stacked with) the second radiator A 318a in the z dimension.

[0065] The first radiator A 308a may be connected and / or coupled to the first feed A 310a and the second feed A 314a. The second radiator A 318a may be connected and / or coupled to the third feed A 312a and the fourth feed A 316a. The first element B 304b may include a respective first radiator B 308b connected and / or coupled to the respective first feed B 310b and the respective second feed B 314b. The first element B 304b may include a respective second radiator B 318b connected and / or coupled to the respective third feed B 312b and the respective fourth feed B 316b. The first feed A 310a may correspond to a first polarization, and the second feed A 314a may correspond to a second polarization. The third feed A 312a may correspond to a second polarization, and the fourth feed A 316a may correspond to the first polarization. Each of the first elements 304a-b may be dual-polarized. In some examples, the first element B 304b may have an opposed (e.g., mirrored) feed arrangement compared to the first element A 304a.

[0066] In this example, each of the second elements 306a-c may include a respective radiator 320a-c. In this example, the radiator A 320a of the second element A 306a may be similar in size in the x and y dimensions to the second radiator A 318a of the first element A 304a. The radiator A 320a of the second element A 306a may be at a different height than the first radiator A 308a and / or the second radiator A 318a of the first element A 304a.

[0067] The radiator A 320a may be connected and / or coupled to the first feed A 322a and the second feed A 324a of the second element A 306a. The second elements B-C 306b-c may each include a respective radiator B-C 320b-c connected and / or coupled to a respective first feed B-C 322b-c and a respective second feed B-C 324b-c. The first feed A 322a of the second element A 306a may correspond to a first polarization, and the second feed A 324a may correspond to a second polarization. Each of the second elements 306a-c may be dual-polarized. The second elements A-C 306a-c may have similar feed arrangements.

[0068] In this example, each of the third elements 344a-b may include a respective first radiator 332a-b and second radiator 342a-b. In this example, the first radiator A 332a is larger than the second radiator A 342a in the x and y dimensions. In this example, the first radiator A 332a is below (e.g., stacked with) the second radiator A 342a in the z dimension.

[0069] The first radiator A 332a may be connected and / or coupled to the first feed A 334a and the second feed A 338a. The second radiator A 342a may be connected and / or coupled to the third feed A 336a and the fourth feed A 340a. The third element B 344b may include a respective first radiator B 332b connected and / or coupled to the respective first feed B 334b ​​and the respective second feed B 338b. The third element B 344b may include a respective second radiator B 342b connected and / or coupled to the respective third feed B 336b and the respective fourth feed B 340b. The first feed A 334a may correspond to a first polarization, and the second feed A 338a may correspond to a second polarization. The third feed A 336a may correspond to a second polarization, and the fourth feed A 340a may correspond to a first polarization. Each of the third elements 344a-b may be dual-polarized. In some examples, the third element B 344b may have an opposed (e.g., mirrored) feed arrangement compared to the third element A 344a. In the example of FIG. 3, each third element 344a includes four feeds. In some examples, one or more third elements may include two feeds.

[0070] The first element A 304a may include a first radiator A 308a and / or a second radiator A 318a embedded in a material (e.g., a support material and / or a dielectric material). The material (e.g., the support material and / or the dielectric material) of the first element A 304a may be located far from the material (e.g., the support material and / or the dielectric material) of the second element A 306a. The material (e.g., the support material and / or the dielectric material) of the third element A 344a may be located far from the material (e.g., the support material and / or the dielectric material) of the second element A 306a.

[0071] The second elements 306a-c may be interleaved with the first elements 304a-d. The first element A 304a may be larger in size in the x-dimension than the second element A 306a. The third element A 344a may be larger in size in the x-dimension than the second element A 306a. The first element A 304a may be similar in size in the x-dimension to the third element A 344a. The third elements 344a-b may be end elements in the antenna 302.

[0072] Each of the first elements 304a-b, second elements 306a-c, and third elements 344a-b may be disposed on the base 326. In some examples, each of the first elements 304a-b, second elements 306a-c, and / or third elements 344a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 326 (e.g., a larger PCB). In some examples, the first elements 304a-b, second elements 306a-c, and / or third elements 344a-b may be implemented within a single PCB that is mounted within the base 326 (e.g., a larger PCB). In some examples, the antenna 302 array may be implemented within a single (e.g., monolithic) PCB.

[0073] In some configurations, each of the first elements 304a-b may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 47.2-48.2 GHz band (e.g., the 48 GHz band) and the 37-40 GHz band (e.g., n260). In some examples, one or more third bands may be supported by one or more third elements (e.g., third elements 344a-b). For example, the third set of bands may include the 47.2-48.2 GHz band (e.g., the 48 GHz band) and the 39.5-43.5 GHz band (e.g., n259). The third set of bands may overlap with the second set of bands. For example, the second set of bands and the third set of bands may include the 48G band. In this example, the second set of bands may be mutually exclusive with the first set of bands. In this example, the first set of bands is lower in frequency than both the second set of bands and the third set of bands.

[0074] In some configurations, each of the second elements 306a-c may be configured to support a second set of bands (e.g., 48G and n260) and a third set of bands (e.g., 48G and n259). For example, each of the second elements 306a-c may support a combination of the second set of bands and the third set of bands. For example, each of the second elements 306a-c may support the second set of bands that are also supported by the first elements 304a-b and the third set of bands that are also supported by the third elements 344a-b. In some examples, each of the second elements 306a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands).

[0075] In some configurations, each of the third elements 344a-b may be configured to support a first set of bands (e.g., n258, n257, and n261) and one or more third bands (e.g., the third set of bands (e.g., 48G and n259)). For example, the antenna 302 may provide a 1 x 4 element array for the first set of bands, a 1 x 5 array for the n259 and n260 bands, and a 1 x 7 element array for the 48G band. The third elements 344a-b may be separated by multiple (e.g., three) second elements 306a-c and / or by multiple (e.g., two) first elements 304a-b. In some examples, the antenna 302 may include non-uniform element spacing for the bands. For example, when the n259 band is being transmitted, the third elements 344a-b and the second elements 306a-c may be active, but the first elements 304a-b may be inactive, creating a larger spacing between the second elements A-B 306a-b than between the third element A 344a and the second element A 306a-c.

[0076] 3 may provide one or more advantages. This example may reduce implementation complexity for the first elements 304a-b and the third elements 344a-b (which may cover a combination of relatively low and high bands). For example, the first elements 304a-b and / or the third elements 344a-b may not need to support all bands, which may help maintain performance in the relatively low bands (e.g., the first set of bands).

[0077] In some examples, an antenna (e.g., antenna 302) may include a third plurality of third elements (e.g., third elements 344a-b), where each of the third elements is dual polarized and configured to support a first set of bands (e.g., the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261)). In some examples, an antenna (e.g., antenna 302) may include a third plurality of third elements (e.g., third elements 344a-b), where each of the third elements is dual-polarized and configured to support only a first set of bands (e.g., the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261)). For example, the example of FIG. 3 may be altered so that the third elements 344a-b may have only two feed points (e.g., two feeds 336a, 340a for third element A 344a and two feeds 336b, 340b for third element B 344b) to support the first set of bands. For example, in some instances, some feeds (eg, feeds 334a, 338a, 334b, 338b) may be omitted.

[0078] FIG. 4 illustrates an example of scanning performance across bands. For example, FIG. 4 shows a plot 446 of gain versus angle for the n259 band for the example antenna 302 described with reference to FIG. 3. As shown in FIG. 4, even with the uneven spacing caused by the placement of the antenna 302 described with reference to FIG. 3, scanning performance for the n259 band was good. Plot 446 shows gain versus a ±45-degree scan angle for the n259 band. For example, a 1×5 array can produce a magnitude (in decibels (dB)) across the angle of excitation at 43.5 GHz (for the n259 band). For example, excitation for elements (from left to right) of the antenna described with reference to FIG. 3 may be implemented according to the representation [1(0), 1(120), 0, 1(3*120), 0, 1(5*120), 1(6*120)], where the first term indicates the magnitude of the excitation and the numbers in parentheses indicate the phase of the excitation at each element with respect to one of the polarizations.

[0079] Figure 5 illustrates a top view of another example antenna 502 according to some of the configurations described herein. The antenna 502 and / or one or more components of the antenna 502 may be examples of corresponding components described with respect to Figures 1A and / or 1B. The antenna 502 shown in Figure 5 is an example of a multi-band dual-polarized shared-aperture interleaved antenna.

[0080] The antenna 502 may include a first plurality of first elements 504a-b, a second plurality of second elements 506a-c, and a third plurality of third elements 544a-b. In this example, two first elements 504a-b, three second elements 506a-c, and two third elements 544a-b are shown.

[0081] In this example, each of the first elements 504a-b may include a respective first radiator 508a-b and second radiator 518a-b. In this example, the first radiator A 508a is larger than the second radiator A 518a in the x and y dimensions. In this example, the first radiator A 508a is below (e.g., stacked with) the second radiator A 518a in the z dimension.

[0082] The first radiator A 508a may be connected and / or coupled to the first feed A 510a and the second feed A 514a. The second radiator A 518a may be connected and / or coupled to the third feed A 512a and the fourth feed 516a. The first element B 504b may include a respective first radiator B 508b connected and / or coupled to the respective first feed B 510b and the respective second feed B 514b. The first element B 504b may include a respective second radiator B 518b connected and / or coupled to the respective third feed B 512b and the respective fourth feed B 516b. The first feed A 510a may correspond to a first polarization, and the second feed A 514a may correspond to a second polarization. The third feed A 512a may correspond to a second polarization, and the fourth feed A 516a may correspond to a first polarization. Each of the first elements 504a-b may be dual-polarized. In some examples, the first element B 504b may have an opposed (e.g., mirrored) feed arrangement compared to the third element A 544a.

[0083] In this example, each of the second elements 506a-c may include a respective radiator 520a-c. In this example, the radiator A 520a of the second element A 506a may be similar in size in the x and y dimensions to the second radiator A 518a of the first element A 504a. The radiator A 520a of the second element A 506a may be at a different height than the first radiator A 508a and / or the second radiator A 518a of the first element A 504a.

[0084] The radiator A 520a may be connected and / or coupled to the first feed A 522a and the second feed A 524a of the second element A 506a. The second elements B-C 506b-c may each include a respective radiator B-C 520b-c connected and / or coupled to a respective first feed B-C 522b-c and a respective second feed B-C 524b-c.

In this example, the first radiator A 532a is larger than the second radiator A 542a in the x and y dimensions. In this example, the first radiator A 532a is below (e.g., stacked with) the second radiator A 542a in the z dimension.

[0086] The first radiator A 532a may be connected and / or coupled to the first feed A 534a and the second feed A 538a.

The third feed A 536a may correspond to a second polarization, and the fourth feed A 540a may correspond to a first polarization. Each of the third elements 544a-b may be dual-polarized. In some examples, the third element B 544b may have an opposed (e.g., mirrored) feed arrangement compared to the first element A 504a.

[0087] The first element A 504a may include a first radiator A 508a and / or a second radiator A 518a embedded in a material (e.g., a support material and / or a dielectric material). The material (e.g., a support material and / or a dielectric material) of the first element A 504a may be located remotely from the material (e.g., a support material and / or a dielectric material) of the second element A 506a. The material (e.g., a support material and / or a dielectric material) of the third element A 544a may be located remotely from the material (e.g., a support material and / or a dielectric material) of the second element C 506c. In some examples, the third elements 544a-b may be separated by the second element C 506c.

[0088] The first elements 504a-b may be interleaved with the second elements A 506a. The third elements 544a-b may be interleaved with the second elements C 506c. The first elements A 504a may be larger in size in the x-dimension than the second elements A 506a. The third elements A 544a may be larger in size in the x-dimension than the second elements A 506a. The first elements A 504a may be similar in size in the x-dimension to the third elements A 544a.

[0089] Each of the first elements 504a-b, second elements 506a-c, and third elements 544a-b may be disposed on the base 526. In some examples, each of the first elements 504a-b, second elements 506a-c, and / or third elements 544a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 526 (e.g., a larger PCB). In some examples, the first elements 504a-b, second elements 506a-c, and / or third elements 544a-b may be implemented within a single PCB that is mounted within the base 526 (e.g., a larger PCB). In some examples, the antenna 502 array may be implemented within a single (e.g., monolithic) PCB.

[0090] In some configurations, each of the first elements 504a-b may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 47.2-48.2 GHz band (e.g., the 48 GHz band) and the 37-40 GHz band (e.g., n260). In this example, the third set of bands includes the 47.2-48.2 GHz band (e.g., the 48 GHz band) and the 39.5-43.5 GHz band (e.g., n259). The third set of bands may overlap with the second set of bands. For example, the second set of bands and the third set of bands may include the 48 GHz band. In this example, the second set of bands may be mutually exclusive from the first set of bands, where the first set of bands is lower in frequency than both the second set of bands and the third set of bands.

[0091] In some configurations, each of the second elements 506a-c may be configured to support a second set of bands (e.g., 48G and n260) and a third set of bands (e.g., 48G and n259). For example, each of the second elements 506a-c may support a combination of the second set of bands and the third set of bands. For example, each of the second elements 506a-c may support the second set of bands that are also supported by the first elements 504a-b and the third set of bands that are also supported by the third elements 544a-b. In some examples, each of the second elements 506a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands).

[0092] In some configurations, each of the third elements 544a-b may be configured to support a first set of bands (e.g., n258, n257, and n261) and a third set of bands (e.g., 48G and n259). For example, the antenna 502 may provide a 1 x 4 element array for the first set of bands, a 1 x 5 array for the n259 and n260 bands, and a 1 x 7 element array for the 48G band. The third elements 544a-b may be separated by a second element C 506c and / or the first elements 504a-b may be separated by a second element A 506a.

[0093] 5 may provide one or more advantages. This example may reduce implementation complexity for the first elements 504a-b and the third elements 544a-b (which may cover a combination of relatively low and high bands). For example, the first elements 504a-b and / or the third elements 544a-b may not need to support all bands, which may help maintain performance in the relatively low bands (e.g., the first set of bands).

[0104] The first element A 604a may include a first radiator A 608a and / or a second radiator A 618a embedded in a material (e.g., a support material and / or a dielectric material). The material (e.g., a support material and / or a dielectric material) of the first element A 604a may be located far from the material (e.g., a support material and / or a dielectric material) of the second element A 606a. The material (e.g., a support material and / or a dielectric material) of the third element A 644a may be located far from the material (e.g., a support material and / or a dielectric material) of the second element C 606c. In some examples, the third element 644a and the fourth element 660a may be separated by the second element C 606c.

[0105] The first elements 604a-b may be interleaved with the second elements A 606a. The first elements A 604a may be larger in size in the x-dimension than the second elements A 606a.

The first elements A 604a may be similar in size in the x-dimension to the third elements A 644a and / or the fourth elements A 660a.

[0106] Each of the first elements 604a-b, second elements 606a-c, third element 644a, and fourth element 660a may be disposed on the base 626. In some examples, each of the first elements 604a-b, second elements 606a-c, third element 644a, and / or fourth element 660a may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 626 (e.g., a larger PCB). In some examples, the first elements 604a-b, second elements 606a-c, third element 644a, and / or fourth element 660a may be implemented within a single PCB that is mounted within the base 626 (e.g., a larger PCB). In some examples, the antenna 602 array may be implemented within a single (e.g., monolithic) PCB.

[0107] In some configurations, each of the first elements 604a-b may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 47.2-48.2 GHz band (e.g., the 48 GHz band) and the 37-40 GHz band (e.g., n260). In this example, the third set of bands includes the 47.2-48.2 GHz band (e.g., the 48 GHz band) and the 39.5-43.5 GHz band (e.g., n259).

In this example, the fourth set of bands includes the 37-40 GHz band (e.g., n260) and the 39.5-43.5 GHz band (e.g., n259). The fourth set of bands may overlap with the second set of bands and / or the third set of bands. For example, the second set of bands and the fourth set of bands may include the n260 band. In this example, the second set of bands may be mutually exclusive with the first set of bands. In this example, the first set of bands is lower in frequency than the second set of bands, the third set of bands, and the fourth set of bands.

[0108] In some configurations, each of the second elements 606a-c may be configured to support a second set of bands (e.g., 48G and n260), a third set of bands (e.g., 48G and n259), and a fourth set of bands (e.g., n260 and n259). For example, each of the second elements 606a-c may support a combination of the second set of bands, the third set of bands, and the fourth set of bands. For example, each of the second elements 606a-c may support the second set of bands that are also supported by the first elements 604a-b, the third set of bands that are also supported by the third element 644a, and the fourth set of bands that are also supported by the fourth element 660a. In some examples, each of the second elements 606a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands).

[0109] In some configurations, the third element 644a may be configured to support a first set of bands (e.g., n258, n257, and n261) and a third set of bands (e.g., 48G and n259). In some configurations, the fourth element 660a may be configured to support a first set of bands (e.g., n258, n257, and n261) and a fourth set of bands (e.g., n260 and n259). For example, the antenna 602 may provide a 1×4 element array for the first set of bands, a 1×5 array for the n259 band, and a 1×6 element array for the 48G band and the n260 band. Note that other implementations are possible using different band combinations.

[0110] Figure 7A is a diagram illustrating a top view of another example antenna 702 according to some of the configurations described herein. Figure 7B is a diagram illustrating an elevation view of the antenna 702 of Figure 7A. Figures 7A and 7B are described together. The antenna 702 and / or one or more components of the antenna 702 may be examples of corresponding components described with respect to Figures 1A and / or 1B. The antenna 702 shown in Figures 7A and 7B is an example of a multi-band dual-polarized aperture-sharing interleaved antenna.

[0111] The antenna 702 may include a first plurality of first elements 704a-d and a second plurality of second elements 706a-d. In this example, four first elements 704a-d and four second elements 706a-d are shown. In this example, the antenna 702 is 26.2 mm wide and 3.5 mm long. In other examples, other dimensions may be used.

[0112] In this example, each of the first elements 704a-d may include a respective first radiator 708a-d and second radiator 718a-d. In this example, the first radiator A 708a is larger than the second radiator A 718a in the x and y dimensions. In this example, the first radiator A 708a is below (e.g., stacked with) the second radiator A 718a in the z dimension.

[0113] The first radiator A 708a may be connected and / or coupled to the first feed A 710a and the second feed A 714a. The second radiator A 718a may be connected and / or coupled to the third feed A 712a and the fourth feed 716a. The first elements B-D 704b-d may each include a respective first radiator B-D 708b-d connected and / or coupled to a respective first feed B-D 710b-d and a respective second feed B-D 714b-d. The first elements B-D 704b-d may each include a respective second radiator B-D 718b-d connected and / or coupled to a respective third feed B-D 712b-d and a respective fourth feed B-D 716b-d. The first feed A 710a may correspond to a first polarization, and the second feed A 714a may correspond to a second polarization (e.g., for a first band or a first set of bands). The third feed A 712a may correspond to a second polarization, and the fourth feed A 716a may correspond to a first polarization (e.g., for a second band or a second set of bands). Each of the first elements 704a-d may be dual-polarized. In some examples, the first elements C-D 704c-d may have an opposed (e.g., mirrored) feed arrangement compared to the first elements A-B 704a-b.

[0114] In this example, each of the second elements 706a-d may include a respective radiator 720a-d. In this example, the radiator A 720a of the second element A 706a may be similar in size in the x and y dimensions to the second radiator A 718a of the first element A 704a. The radiator A 720a of the second element A 706a may be at a different height than the first radiator A 708a and / or the second radiator A 718a of the first element A 704a.

[0115] Radiator A 720a may be connected and / or coupled to first feed A 722a and second feed A 724a of second element A 706a. Second elements B-D 706b-d may each include a respective radiator B-D 720b-d connected and / or coupled to a respective first feed B-D 722b-d and a respective second feed B-D 724b-d. First feed A 722a of second element A 706a may correspond to a first polarization, and second feed A 724a may correspond to a second polarization (e.g., for a second band or a second set of bands). Each of second elements 706a-d may be dual-polarized. The second elements C-D 706c-d may have an opposed (eg, mirrored) feed arrangement compared to the second elements A-B 706a-b.

[0116] The first element A 704a may include a first radiator A 708a and / or a second radiator A 718a embedded in a material (e.g., a support material and / or a dielectric material). The material (e.g., the support material and / or the dielectric material) of the first element A 704a may be located remotely from the material (e.g., the support material and / or the dielectric material) of the second element A 706a.

[0117] The second elements 706a-d may be interleaved with the first elements 704a-d. The first element A 704a may be larger in size in the x dimension than the second element A 706a.

[0118] Each of the first elements 704a-d and second elements 706a-d may be disposed on the base 726. In some examples, each of the first elements 704a-d and / or second elements 706a-d may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 726 (e.g., a larger PCB). In some examples, the first elements 704a-d and / or second elements 706a-d may be implemented within a single PCB that is mounted within the base 726 (e.g., a larger PCB). In some examples, the antenna 702 array may be implemented within a single (e.g., monolithic) PCB.

[0119] In some configurations, each of the first elements 704a-d may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 37-40 GHz band (e.g., n260) and / or the 39.5-43.5 GHz band (e.g., n259). In some examples, only the second elements 706a-d may support the 47.2-48.2 GHz band (e.g., the 48 GHz band). In this example, the second set of bands may be mutually exclusive from the first set of bands. In this example, the first set of bands is lower in frequency than the second set of bands.

[0120] In some configurations, each of the second elements 706a-d may be configured to support a second set of bands. For example, each of the second elements 706a-d may support a second set of bands that are also supported by the first elements 704a-d. In some examples, each of the second elements 706a-d may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands). In some examples, the number of elements for the first set of bands (e.g., four) may be fewer than the number of elements for the second set of bands (e.g., eight). For example, the antenna 702 may provide a 1 x 4 element array for the first set of bands, a 1 x 8 element array for the second set of bands, and a 1 x 4 array for the 48G band.

[0121] In this example, the first element spacing 728 for the first set of bands (e.g., 6.6 millimeters (mm)) may be larger than the second element spacing 730 for the second set of bands (e.g., 3.3 mm). For example, the first set of bands may be supported by the first elements 704a-d and not by the second set of elements 706a-d. Thus, the first element spacing 728 for the first set of bands may be the distance between the center of the first element A 704a and the center of the first element B 704b. The first element spacing 728 may range from approximately 0.53 to 0.65λ for the first set of bands, where λ is the signal wavelength. The second set of bands may be supported by each of the first elements 704a-d and the second elements 706a-d. Thus, the second element spacing 730 for the second set of bands may be the distance between the center of the first element A 704a and the center of the second element A 706a. The second element spacing 730 may range from approximately 0.41 to 0.48λ for the n259 and n260 bands. In this example, a third element spacing 748 (e.g., 6.6 millimeters (mm)) may be used for the 48G band between the centers of the second elements 706a-d. The third element spacing 748 may be approximately 1.06λ for the 48G band.

[0122] In this example, first elements 704a-d (for the first set of bands and the second set of bands) and second elements 706a-d (for the second set of bands) may support multiple bands through aperture sharing. Because element spacing 748 is approximately 1.06λ for the 48G band, grating lobes may occur for the 48G band. In some approaches, element spacing may be targeted to be approximately 0.5λ. However, in the example of FIG. 7, good scanning performance is still achieved with grating lobes.

[0123] Figure 8 illustrates a top view of another example antenna 802 according to some of the configurations described herein. The antenna 802 and / or one or more components of the antenna 802 may be examples of corresponding components described with respect to Figures 1A and / or 1B.

The material (e.g., the support material and / or the dielectric material) of the third element A 844a may be located far from the material (e.g., the support material and / or the dielectric material) of the second element A 806a.

[0133] Each of the first elements 804a-c, second elements 806a-c, and third elements 844a-b may be disposed on the base 826. In some examples, each of the first elements 804a-c, second elements 806a-c, and / or third elements 844a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 826 (e.g., a larger PCB). In some examples, the first elements 804a-c, second elements 806a-c, and / or third elements 844a-b may be implemented within a single PCB that is mounted within the base 826 (e.g., a larger PCB). In some examples, the antenna 802 array may be implemented within a single (e.g., monolithic) PCB.

[0134] In some configurations, each of the first elements 804a-c may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 37-40 GHz band (e.g., n260) and / or the 39.5-43.5 GHz band (e.g., n259). In some examples, the second elements 806a-c and / or the third elements 844a-b may support the 47.2-48.2 GHz band (e.g., the 48 GHz band). In some examples, one or more third bands may be supported by one or more third elements (e.g., third elements 844a-b). For example, the third band may include the 47.2-48.2 GHz band (e.g., the 48 GHz band). In some examples, the third elements 844a-b may support a first set of bands. In this example, the second set of bands may be mutually exclusive from the first set of bands. In this example, the first set of bands are lower in frequency than the second set of bands.

[0135] In some configurations, each of the second elements 806a-c may be configured to support a second set of bands. For example, each of the second elements 806a-c may support a second set of bands that are also supported by the first elements 804a-c. In some examples, each of the second elements 806a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands). In some examples, the number of elements for the first set of bands (e.g., five) may be fewer than the number of elements for the second set of bands (e.g., six). For example, the antenna 802 may provide a 1 x 5 element array for the first set of bands, a 1 x 6 element array for the second set of bands, and a 1 x 5 array for a third band (e.g., 48G).

[0136] In this example, the first element spacing 828 (e.g., 6.6 mm) for the first set of bands may be larger than the second element spacing 830 (e.g., 3.3 mm) for the third band (e.g., 48 G). For example, the first set of bands may be supported by the first elements 804 a-c and not by the second set of elements 806 a-c. Thus, the first element spacing 828 for the first set of bands may be the distance between the center of the third element A 844 a and the center of the first element A 804 a and / or the center of the first element A 804 a and the center of the first element B 804 b. The first element spacing 828 may range from approximately 0.53 to 0.65 λ for the first set of bands, where λ is the signal wavelength. The second set of bands may be supported by each of the first elements 804 a-c and the second elements 806 a-c. The second element spacing 830 for the third band (e.g., 48G) may be the distance between the center of the third element A 844a and the center of the second element A 806a. The second element spacing 830 may be approximately 0.53λ for the 48G band. In this example, the third element spacing 848 (e.g., 6.6 mm) may be used for the 48G band between the centers of the second elements 806a-c. The third element spacing 848 may be approximately 1.06λ for the 48G band. In this example, the fourth element spacing 852 (e.g., 4.7 mm) may be used for the first set of bands (e.g., approximately 0.42λ) between the centers of the first element C 804c and the third element B 844b. In this example, first elements 804a-c (for the first set of bands and the second set of bands), second elements 806a-c (for the second set of bands and / or the third band (e.g., 48G)), and third elements 844a-b (for the first set of bands and the third band) may support multiple bands through aperture sharing.

[0147] Each of the first elements 904a-b, second elements 906a-c, and third elements 944a-c may be disposed on the base 926. In some examples, each of the first elements 904a-b, second elements 906a-c, and / or third elements 944a-c may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 926 (e.g., a larger PCB). In some examples, the first elements 904a-b, second elements 906a-c, and / or third elements 944a-c may be implemented within a single PCB that is mounted within the base 926 (e.g., a larger PCB). In some examples, the antenna 902 array may be implemented within a single (e.g., monolithic) PCB.

[0148] In some configurations, each of the first elements 904a-b may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 37-40 GHz band (e.g., n260) and / or the 39.5-43.5 GHz band (e.g., n259). In some examples, the second elements 906a-c and / or the third elements 944a-c may support the 47.2-48.2 GHz band (e.g., the 48 GHz band). In some examples, one or more third bands may be supported by one or more third elements (e.g., third elements 944a-b). For example, the third band may include the 47.2-48.2 GHz band (e.g., the 48 GHz band). In some examples, the third elements 944a-c may support a first set of bands. In this example, the second set of bands may be mutually exclusive from the first set of bands. In this example, the first set of bands are lower in frequency than the second set of bands.

[0149] In some configurations, each of the second elements 906a-c may be configured to support a second set of bands. For example, each of the second elements 906a-c may support a second set of bands that are also supported by the first elements 904a-b. In some examples, each of the second elements 906a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands). In some examples, the number of elements (e.g., 5) for the first set of bands may be the same as the number of elements (e.g., 5) for the second set of bands. For example, the antenna 902 may provide a 1 x 5 element array for the first set of bands, a 1 x 5 element array for the second set of bands, and a 1 x 6 array for the 48G band.

[0150] In this example, the first element spacing 928 (e.g., 6.6 mm) for the first set of bands may be larger than the second element spacing 930 (e.g., 3.3 mm) for the third band (e.g., 48 G). For example, the first set of bands may be supported by the first elements 904a-b and not by the second set of elements 906a-c. Thus, the first element spacing 928 for the first set of bands may be the distance between the center of the third element A 944a and the center of the first element A 904a, and / or the distance between the center of the first element A 904a and the center of the first element B 904b. The first element spacing 928 may range from approximately 0.53 to 0.65λ for the first set of bands, where λ is the signal wavelength. The second set of bands may be supported by each of the first elements 904a-b and the second elements 906a-c. The second element spacing 930 for the third band (e.g., 48G) may be the distance between the center of third element A 944a and the center of second element A 906a. The second element spacing 930 may be approximately 0.53λ for the 48G band. In this example, a third element spacing 948 (e.g., 6.6 mm) may be used for the 48G band between the centers of second elements 906a-c. The third element spacing 948 may be approximately 1.06λ for the 48G band. In this example, a fourth element spacing 952 (e.g., 4.7 mm) may be used for the first set of bands (e.g., approximately 0.42λ) and the 48G band (e.g., approximately 0.75λ) between the centers of third elements B-C 944b-c. In this example, first elements 904a-b (for the first set of bands and the second set of bands), second elements 906a-c (for the second set of bands and / or the third band (e.g., 48G)), and third elements 944a-c (for the first set of bands and the third band) may support multiple bands through aperture sharing.

Other elements (e.g., first element A 1004a and second element B 1006, first element B 1004b and second element C 1006c, and / or third element B 1044b and second element D 1006d) may be combined and / or in some examples may be included in one printed circuit board.

[0160] The second elements A-C 1006a-c may be interleaved with the first elements 1004a-b. The first element A 1004a may be larger in size in the x-dimension than the second element A 1006a. The third elements A-B 1044a-b may be larger in size in the x-dimension than the second element A 1006a. The first element A 1004a may be similar in size in the x-dimension to the third element A 1044a.

[0161] Each of the first elements 1004a-b, second elements 1006a-d, and third elements 1044a-b may be disposed on the base 1026. In some examples, each of the first elements 1004a-b, second elements 1006a-d, and / or third elements 1044a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 1026 (e.g., a larger PCB). In some examples, the first elements 1004a-b, second elements 1006a-d, and / or third elements 1044a-b may be implemented within a single PCB that is mounted within the base 1026 (e.g., a larger PCB). In some examples, the antenna 1002 array may be implemented within a single (e.g., monolithic) PCB.

[0162] In some configurations, each of the first elements 1004a-b may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 37-40 GHz band (e.g., n260) and / or the 39.5-43.5 GHz band (e.g., n259). In some examples, the second elements 1006a-d and / or the third elements 1044a-b may support the 47.2-48.2 GHz band (e.g., the 48 GHz band, n262). In some examples, one or more third bands may be supported by one or more third elements (e.g., third elements 1044a-b). For example, the third band may include the 47.2-48.2 GHz band (e.g., the 48 GHz band, n262). In some examples, the third elements 1044a-b may support a first set of bands. In this example, the second set of bands may be mutually exclusive from the first set of bands. In this example, the first set of bands is lower in frequency than the second set of bands. In some examples, the third band may be separated from the second set of bands by 3 GHz or more. In some examples described herein, each element may support only a subset of all bands supported by the antenna. For example, in some implementations, none of the elements may support all of the bands supported by the antenna.

[0163] In some configurations, each of the second elements 1006a-d may be configured to support a second set of bands. For example, each of the second elements 1006a-d may support a second set of bands that are also supported by the first elements 1004a-b. In some examples, each of the second elements 1006a-d may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands). In some examples, the number of elements for the first set of bands (e.g., four) may be different from the number of elements for the second set of bands and / or the third band (e.g., six). For example, the antenna 1002 may provide a 1 x 4 element array for the first set of bands, a 1 x 6 element array for the second set of bands, and a 1 x 6 array for the 48G band.

[0164] In this example, the first element spacing 1028 (e.g., 6.6 mm) for the first set of bands may be larger than the second element spacing 1030 (e.g., 3.3 mm) for the third band (e.g., 48 G). For example, the first set of bands may be supported by the first elements 1004a-b and not by the second set of elements 1006a-d. Thus, the first element spacing 1028 for the first set of bands may be the distance between the center of the third element A 1044a and the center of the first element A 1004a, and / or the distance between the center of the first element A 1004a and the center of the first element B 1004b. The first element spacing 1028 may range from approximately 0.53 to 0.65λ for the first set of bands, where λ is the signal wavelength. A second set of bands may be supported by each of the first elements 1004a-b and the second elements 1006a-d. A second element spacing 1030 for a third band (e.g., 48G) may be the distance between the center of the third element A 1044a and the center of the second element A 1006a. The second element spacing 1030 may be approximately 0.53λ for the 48G band. In this example, a third element spacing 1048 (e.g., 6.6 mm) may be used for the 48G band between the centers of the second elements 1006a-d. The third element spacing 1048 may be approximately 1.06λ for the 48G band. In this example, first elements 1004a-b (for the first set of bands and the second set of bands), second elements 1006a-d (for the second set of bands and / or the third band (e.g., 48G)), and third elements 1044a-b (for the first set of bands and the third band) may support multiple bands through aperture sharing.

[0165] In some examples, the third element A 1044a includes a first radiator A 1032a below the second radiator A 1042a but not the radiator A 1020a of the second element A 1006a, so the second radiator A 1042a of the third element A 1044a may be larger than the radiator A 1020a of the second element A 1006a. For example, the first radiator A 1032a (e.g., a low-band patch) of the third element A 1044a may serve as a ground plane for the second radiator A 1042a (e.g., a high-band patch). A radiator (e.g., a patch) closer to the ground plane may be larger than a radiator (e.g., a patch) farther away from the ground plane to radiate at the same frequency. In the example shown in FIG. 10B, the elements are equal or approximately equal in height. In some instances, elements that are combined on a PCB may be equal or approximately equal in height.

[0166] In some example antennas described herein, one or more elements may include one or more posts connecting one or more radiators to ground. In FIG. 10B , for example, first elements 1004a-b may include respective posts 1019a-b connecting respective radiators 1008a-b to ground. Second elements 1006a-d may include respective posts 1021a-d connecting respective radiators 1020a-d to ground. Third elements 1044a-b may include respective posts 1023a-b connecting respective radiators 1032a-b to ground. Other example elements, described with respect to other figures, may similarly include one or more posts connecting one or more radiators to ground in some implementations. In some examples, the posts may be connected approximately to the center of the patch.

[0167] FIG. 11 is a diagram illustrating an elevation view of another example of an antenna 1102 according to some of the configurations described herein. The antenna 1102 and / or one or more components of the antenna 1102 may be examples of corresponding components described with respect to FIGS. 1A and / or 1B. The antenna 1102 shown in FIG. 11 is an example of a multi-band dual-polarized shared-aperture interleaved antenna. FIG. 11 illustrates an alternative configuration of the antenna 1002 described with respect to FIG. 10A. For example, the components described with respect to FIG. 10A may be similar to the corresponding components described with respect to FIG. 11. However, the components described in FIG. 11 may vary in one or more aspects compared to the components described with respect to FIG. 10B. For example, some of the components of FIG. 11 may vary with respect to the z (e.g., height) dimension.

[0168] 11, the elements may have different heights. For example, the second elements 1106a-d have a smaller height compared to the third elements 1144a-b and / or the first elements 1104a-b. In some examples, some elements (e.g., elements supporting a higher band or bands) may have a shorter height, which may shorten the probe length and improve performance.

[0169] The antenna 1102 may include a first plurality of first elements 1104a-b, a second plurality of second elements 1106a-d, and a third plurality of third elements 1144a-b. In this example, two first elements 1104a-b, four second elements 1106a-d, and two third elements 1144a-b are shown. In this example, the antenna 1102 is 3.5 mm in length. In other examples, other dimensions may be used.

[0170] In this example, each of the first elements 1104a-b may include a respective first radiator 1108a-b and second radiator 1118a-b. In this example, the first radiator A 1108a is larger than the second radiator A 1118a in the x and y dimensions. In this example, the first radiator A 1108a is below (e.g., stacked with) the second radiator A 1118a in the z dimension.

[0171] The first radiator A 1108a may be connected and / or coupled to a first feed A (not shown) and a second feed A 1114a of the first element A 1104a.

The first feed A of the first element A 1104a may correspond to a first polarization, and the second feed A 1114a may correspond to a second polarization. The third feed A of the first element A 1104a may correspond to a second polarization, and the fourth feed A 1116a may correspond to the first polarization. Each of the first elements 1104a-b may be dual-polarized. In some examples, the first element B 1104b may have a similar feed arrangement compared to the first element A 1104a.

[0172] In this example, each of the second elements 1106a-d may include a respective radiator 1120a-d. In this example, the radiator A 1120a of the second element A 1106a may be smaller in size in the x and / or y dimensions than the second radiator A 1142a of the third element A 1144a. The radiator A 1120a of the second element A 1106a may be at a different height than the first radiator A 1108a and / or the second radiator A 1118a of the first element A 1104a.

[0173] The radiator A 1120a may be connected and / or coupled to the first feed A (not shown) and second feed A 1124a of the second element A 1106a. The second elements B-D 1106b-d may each include a respective radiator B-D 1120b-d connected and / or coupled to the respective first feed B-D (not shown) and second feed B-D 1124b-d of the respective second element B-D 1106b-d. The first feed A of the second element A 1106a may correspond to a first polarization, and the second feed A 1124a may correspond to a second polarization.

In this example, the first radiator A 1132a is larger than the second radiator A 1142a in the x and y dimensions. In this example, the first radiator A 1132a is below (e.g., stacked with) the second radiator A 1142a in the z dimension.

[0175] The first radiator A 1132a may be connected and / or coupled to a first feed A (not shown) and a second feed A 1138a of the third element A 1144a. The second radiator A 1142a may be connected and / or coupled to a third feed A (not shown) and a fourth feed 1140a of the third element A 1144a. The third element B 1144b may include a first radiator B 1132b connected and / or coupled to a first feed B (not shown) and a second feed B 1138b of the third element B 1144b. The third element B 1144b may include a second radiator B 1142b connected and / or coupled to a third feed B (not shown) and a fourth feed B 1140b of the third element B 1144b. The first feed A of the third element A 1144a may correspond to a first polarization, and the second feed A 1138a may correspond to a second polarization. The third feed A of the third element A 1144a may correspond to a second polarization, and the fourth feed A 1140a may correspond to a first polarization. Each of the third elements 1144a-b may be dual-polarized. In some examples, the third element B 1144b may have a similar feed arrangement compared to the third element A 1144a.

[0176] The first element A 1104a may include a first radiator A 1108a and / or a second radiator A 1118a embedded in a material (e.g., a support material and / or a dielectric material). In some examples, two or more elements may be combined or separated on a printed circuit board. For example, the material (e.g., a support material and / or a dielectric material) of the first element A 1104a may be located far from the material (e.g., a support material and / or a dielectric material) of the second element A 1106a. In some examples, the third element A 1144a and the second element A 1106a may be combined on one printed circuit board. For example, the materials of the third element A 1144a and the second element A 1106a may be combined and / or included within one printed circuit board. Other elements (e.g., first element A 1104a and second element B 1106, first element B 1104b and second element C 1106c, and / or third element B 1144b and second element D 1106d) may be combined and / or in some examples may be included in one printed circuit board.

[0177] The second elements A-C 1106a-c may be interleaved with the first elements 1104a-b. The first element A 1104a may be larger in size in the x-dimension than the second element A 1106a. The third elements A-B 1144a-b may be larger in size in the x-dimension than the second element A 1106a. The first element A 1104a may be similar in size in the x-dimension to the third element A 1144a.

[0178] Each of the first elements 1104a-b, second elements 1106a-d, and third elements 1144a-b may be disposed on the base 1126. In some examples, each of the first elements 1104a-b, second elements 1106a-d, and / or third elements 1144a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 1126 (e.g., a larger PCB). In some examples, the first elements 1104a-b, second elements 1106a-d, and / or third elements 1144a-b may be implemented within a single PCB that is mounted within the base 1126 (e.g., a larger PCB). In some examples, the antenna 1102 array may be implemented within a single (e.g., monolithic) PCB.

[0179] In some examples, the first elements 1104a-b, second elements 1106a-d, and / or third elements 1144a-b may be configured to support bands as described with respect to FIG. 10A, or may be different. In some examples, the element spacing may be implemented as described with respect to FIG. 10A, or may be different. In some examples, the antenna 1102 may support aperture sharing as described with respect to FIG. 10A. In some examples, one or more aspects of the antenna 1102 may be similarly implemented as described with respect to FIG. 10A.

[0180] Figure 12A is a diagram showing a top view of another example antenna 1202 according to some of the configurations described herein. Figure 12B is a diagram showing an elevation view of the antenna 1202 of Figure 12A. Figures 12A and 12B are described together. The antenna 1202 and / or one or more components of the antenna 1202 may be examples of corresponding components described with respect to Figures 1A and / or 1B. The antenna 1202 shown in Figure 12A is an example of a multi-band dual-polarized shared-aperture interleaved antenna.

[0181] The antenna 1202 may include a first plurality of first elements 1204a-b, a second plurality of second elements 1206a-d, and a third plurality of third elements 1244a-b. In this example, two first elements 1204a-b, four second elements 1206a-d, and two third elements 1244a-b are shown. In this example, the antenna 1202 is 3.5 mm long. In this example, the antenna 1202 is 27.2 mm wide. In other examples, other dimensions may be used.

[0182] In this example, each of the first elements 1204a-b may include a respective first radiator 1208a-b and second radiator 1218a-b. In this example, the first radiator A 1208a is larger than the second radiator A 1218a in the x and y dimensions. In this example, the first radiator A 1208a is below (e.g., stacked with) the second radiator A 1218a in the z dimension.

[0183] The first radiator A 1208a may be connected and / or coupled to the first feed A 1210a and the second feed A 1214a. The second radiator A 1218a may be connected and / or coupled to the third feed A 1212a and the fourth feed 1216a. The first element B 1204b may include a respective first radiator B 1208b connected and / or coupled to the respective first feed B 1210b and the respective second feed B 1214b. The first element B 1204b may include a respective second radiator B 1218b connected and / or coupled to the respective third feed B 1212b and the respective fourth feed B 1216b. The first feed A 1210a may correspond to a first polarization, and the second feed A 1214a may correspond to a second polarization. The third feed A 1212a may correspond to a second polarization, and the fourth feed A 1216a may correspond to the first polarization. Each of the first elements 1204a-b may be dual-polarized. In some examples, the first element B 1204b may have an opposed (e.g., mirrored) feed arrangement compared to the first element A 1204a.

[0184] In this example, each of the second elements 1206a-d may include a respective radiator 1220a-d. In this example, the radiator A 1220a of the second element A 1206a may be smaller in size in the x and / or y dimensions than the second radiator A 1242a of the third element A 1244a. The radiator A 1220a of the second element A 1206a may be at a different height than the first radiator A 1208a and / or the second radiator A 1218a of the first element A 1204a.

[0185] The radiator A 1220a may be connected and / or coupled to the first feed A 1222a and the second feed A 1224a of the second element A 1206a. The second elements B-D 1206b-d may each include a respective radiator B-D 1220b-d connected and / or coupled to a respective first feed B-D 1222b-d and a respective second feed B-D 1224b-d. The first feed A 1222a of the second element A 1206a may correspond to a first polarization, and the second feed A 1224a may correspond to a second polarization. Each of the second elements 1206a-d may be dual-polarized. The second elements A-D 1206a-d may have similar feed arrangements. In the example of FIG. 12B , each second element 1206a-d shows a dotted line representing a metal dummy between the respective radiator 1220a-d (e.g., a driven patch) and a parasitic radiator (e.g., a parasitic patch). In some examples, the metal dummy may be disposed below the radiator 1220a-d or intermediate the respective radiator 1220a-d and the parasitic radiator without a significant adverse effect on performance. If the metal dummy is disposed beyond the edge of the radiator, the metal dummy may affect performance unless it is spaced far from the edge. In some examples, the metal dummy may cause a loading effect that may lower the radiator operating frequency and / or possibly increase bandwidth. At a sufficient distance from the radiator, the metal dummy may not significantly degrade performance. Although not visible in FIG. 12 , the metal dummy may therefore be disposed near the edge of the PCB. In some examples, each of the metal dummies is sized so as not to radiate a significant amount of energy at the operating frequency of the respective device.

[0186] In this example, each of the third elements 1244a-b may include a respective first radiator 1232a-b and second radiator 1242a-b. In this example, the first radiator A 1232a is larger than the second radiator A 1242a in the x and y dimensions. In this example, the first radiator A 1232a is below (e.g., stacked with) the second radiator A 1242a in the z dimension.

[0187] The first radiator A 1232a may be connected and / or coupled to the first feed A 1234a and the second feed A 1238a. The second radiator A 1242a may be connected and / or coupled to the third feed A 1236a and the fourth feed 1240a. The third element B 1244b may include a first radiator B 1232b connected and / or coupled to the first feed B 1234b and the second feed B 1238b. The third element B 1244b may include a second radiator B 1242b connected and / or coupled to the third feed B 1236b and the fourth feed B 1240b. The first feed A 1234a may correspond to a first polarization, and the second feed A 1238a may correspond to a second polarization. The third feed A 1236a may correspond to a second polarization, and the fourth feed A 1240a may correspond to a first polarization. Each of the third elements 1244a-b may be dual polarized. In some examples, the third element B 1244b may have an opposed (e.g., mirrored) feed arrangement compared to the third element A 1244a.

[0188] The first element A 1204a may include a first radiator A 1208a and / or a second radiator A 1218a embedded in a material (e.g., a support material and / or a dielectric material). In some examples, two or more elements may be combined or separated on a printed circuit board. For example, the material (e.g., a support material and / or a dielectric material) of the first element A 1204a may be located far from the material (e.g., a support material and / or a dielectric material) of the second element A 1206a. In some examples, the third element A 1244a and the second element A 1206a may be combined on a single printed circuit board. For example, the materials of the third element A 1244a and the second element A 1206a may be combined and / or included within a single printed circuit board. Other elements (e.g., first element A 1204a and second element B 1206, first element B 1204b and second element C 1206c, and / or third element B 1244b and second element D 1206d) may be combined and / or in some examples may be included in one printed circuit board.

[0189] The second elements A-C 1206a-c may be interleaved with the first elements 1204a-b. The first element A 1204a may be larger in size in the x-dimension than the second element A 1206a. The third elements A-B 1244a-b may be larger in size in the x-dimension than the second element A 1206a. The first element A 1204a may be similar in size in the x-dimension to the third element A 1244a.

[0190] Each of the first elements 1204a-b, second elements 1206a-d, and third elements 1244a-b may be disposed on the base 1226. In some examples, each of the first elements 1204a-b, second elements 1206a-d, and / or third elements 1244a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 1226 (e.g., a larger PCB). In some examples, the first elements 1204a-b, second elements 1206a-d, and / or third elements 1244a-b may be implemented within a single PCB that is mounted within the base 1226 (e.g., a larger PCB). In some examples, the antenna 1202 array may be implemented within a single (e.g., monolithic) PCB.

[0191] In some configurations, each of the first elements 1204a-b may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 37-40 GHz band (e.g., n260) and / or the 39.5-43.5 GHz band (e.g., n259). In some examples, the second elements 1206a-d and / or the third elements 1244a-b may support the 47.2-48.2 GHz band (e.g., the 48 GHz band, n262). In some examples, one or more third bands may be supported by one or more third elements (e.g., third elements 1244a-b). For example, the third band may include the 47.2-48.2 GHz band (e.g., the 48 GHz band, n262). In some examples, the third elements 1244a-b may support a first set of bands. In this example, the second set of bands may be mutually exclusive from the first set of bands. In this example, the first set of bands are lower in frequency than the second set of bands.

[0192] In some configurations, each of the second elements 1206a-d may be configured to support a second set of bands. For example, each of the second elements 1206a-d may support a second set of bands that are also supported by the first elements 1204a-b. In some examples, each of the second elements 1206a-d may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands). In some examples, the number of elements for the first set of bands (e.g., four) may be different from the number of elements for the second set of bands and / or the third band (e.g., six). For example, the antenna 1202 may provide a 1 x 4 element array for the first set of bands, a 1 x 6 element array for the second set of bands, and a 1 x 6 array for the third (e.g., 48G) band.

[0193] In this example, the first element spacing 1228 (e.g., 6.6 mm) for the first set of bands may be larger than the second element spacing 1230 (e.g., 3.3 mm) for the third band (e.g., 48 G). For example, the first set of bands may be supported by the first elements 1204a-b and not by the second set of elements 1206a-d. Thus, the first element spacing 1228 for the first set of bands may be the distance between the center of the third element A 1244a and the center of the first element A 1204a, and / or the distance between the center of the first element A 1204a and the center of the first element B 1204b. The first element spacing 1228 may range from approximately 0.53 to 0.65λ for the first set of bands, where λ is the signal wavelength. A second set of bands may be supported by each of the first elements 1204a-b and the second elements 1206a-d. The second element spacing 1230 for the third band (e.g., 48G) may be the distance between the center of the third element A 1244a and the center of the second element A 1206a. The second element spacing 1230 may be approximately 0.53λ for the 48G band. In this example, a third element spacing 1248 (e.g., 6.6 mm) may be used for the 48G band between the centers of the second elements 1206a-d. The third element spacing 1248 may be approximately 1.06λ for the 48G band. In this example, first elements 1204a-b (for the first set of bands and the second set of bands), second elements 1206a-d (for the second set of bands and / or the third band (e.g., 48G)), and third elements 1244a-b (for the first set of bands and the third band) may support multiple bands through aperture sharing.

[0194] In some examples, the third element A 1244a includes a first radiator A 1232a below the second radiator A 1242a but not the radiator A 1220a of the second element A 1206a, so the second radiator A 1242a of the third element A 1244a may be larger than the radiator A 1220a of the second element A 1206a. For example, the first radiator A 1232a (e.g., a low-band patch) of the third element A 1244a may serve as a ground plane for the second radiator A 1242a (e.g., a high-band patch). A radiator (e.g., a patch) closer to the ground plane may be larger than a radiator (e.g., a patch) farther away from the ground plane to radiate at the same frequency. In the example shown in FIG. 12B, the elements are equal or approximately equal in height. In some instances, elements that are combined on a PCB may be equal or approximately equal in height.

[0195] FIG. 13 is a diagram illustrating an elevation view of another example antenna 1302 according to some of the configurations described herein. The antenna 1302 and / or one or more components of the antenna 1302 may be examples of corresponding components described with respect to FIGS. 1A and / or 1B. The antenna 1302 shown in FIG. 13 is an example of a multi-band dual-polarized shared-aperture interleaved antenna. FIG. 13 illustrates an alternative configuration of the antenna 1202 described with respect to FIG. 12A. For example, the components described with respect to FIG. 12A may be similar to the corresponding components described with respect to FIG. 13. However, the components described in FIG. 13 may vary in one or more aspects compared to the components described with respect to FIG. 12B. For example, some of the components in FIG. 13 may vary with respect to the z (e.g., height) dimension.

[0196] 13, the elements may have different heights. For example, the second elements 1306a-d have a smaller height compared to the third elements 1344a-b and / or the first elements 1304a-b. In some examples, some elements (e.g., elements supporting a higher band or bands) may have a shorter height, which may shorten the probe length and improve performance.

[0197] The antenna 1302 may include a first plurality of first elements 1304a-b, a second plurality of second elements 1306a-d, and a third plurality of third elements 1344a-b. In this example, two first elements 1304a-b, four second elements 1306a-d, and two third elements 1344a-b are shown. In this example, the antenna 1302 is 3.5 mm in length. In other examples, other dimensions may be used.

[0198] In this example, each of the first elements 1304a-b may include a respective first radiator 1308a-b and second radiator 1318a-b. In this example, the first radiator A 1308a is larger than the second radiator A 1318a in the x and y dimensions. In this example, the first radiator A 1308a is below (e.g., stacked with) the second radiator A 1318a in the z dimension.

[0199] The first radiator A 1308a may be connected and / or coupled to a first feed A (not shown) and a second feed A 1314a of the first element A 1304a.

The first element B 1304b may include a respective first radiator B 1308b connected and / or coupled to a respective first feed B (not shown) and a respective second feed B 1314b of the first element B 1304b. The first element B 1304b may include a respective second radiator B 1318b connected and / or coupled to a respective third feed B (not shown) and a respective fourth feed B 1316b of the first element B 1304b. The first feed A of the first element A 1304a may correspond to a first polarization, and the second feed A 1314a may correspond to a second polarization. The third feed A of the first element A 1304a may correspond to a second polarization, and the fourth feed A 1316a may correspond to the first polarization. Each of the first elements 1304a-b may be dual-polarized. In some examples, the first element B 1304b may have an opposed (e.g., mirrored) feed arrangement compared to the first element A 1304a.

[0200] In this example, each of the second elements 1306a-d may include a respective radiator 1320a-d. In this example, the radiator A 1320a of the second element A 1306a may be smaller in size in the x and / or y dimensions than the second radiator A 1342a of the third element A 1344a. The radiator A 1320a of the second element A 1306a may be at a different height than the first radiator A 1308a and / or the second radiator A 1318a of the first element A 1304a.

[0201] Radiator A 1320a may be connected and / or coupled to a first feed A (not shown) and a second feed A 1324a of second element A 1306a. Second elements B-D 1306b-d may each include a respective radiator B-D 1320b-d connected and / or coupled to a respective first feed B-D (not shown) and a respective second feed B-D 1324b-d of the respective second element B-D 1306b-d. The first feed A of second element A 1306a may correspond to a first polarization, and the second feed A 1324a may correspond to a second polarization. Each of second elements 1306a-d may be dual-polarized. Second elements A-D 1306a-d may have similar feed arrangements.

[0202] In this example, each of the third elements 1344a-b may include a respective first radiator 1332a-b and second radiator 1342a-b. In this example, the first radiator A 1332a is larger than the second radiator A 1342a in the x and y dimensions. In this example, the first radiator A 1332a is below (e.g., stacked with) the second radiator A 1342a in the z dimension.

[0203] The first radiator A 1332a may be connected and / or coupled to a first feed A (not shown) and a second feed A 1338a of the third element A 1344a. The second radiator A 1342a may be connected and / or coupled to a third feed A (not shown) and a fourth feed A 1340a of the third element A 1344a. The third element B 1344b may include a first radiator B 1332b connected and / or coupled to a first feed B (not shown) and a second feed B 1338b of the third element B 1344b. The third element B 1344b may include a second radiator B 1342b connected and / or coupled to a third feed B (not shown) and a fourth feed B 1340b of the third element B 1344b. The first feed A of the third element A 1344a may correspond to a first polarization, and the second feed A 1338a may correspond to a second polarization. The third feed A of the third element A 1344a may correspond to a second polarization, and the fourth feed A 1340a may correspond to the first polarization. Each of the third elements 1344a-b may be dual-polarized. In some examples, the third element B 1344b may have an opposed (e.g., mirrored) feed arrangement compared to the third element A 1344a.

[0204] The first element A 1304a may include a first radiator A 1308a and / or a second radiator A 1318a embedded in a material (e.g., a support material and / or a dielectric material). In some examples, two or more elements may be combined or separated on a printed circuit board. For example, the material (e.g., a support material and / or a dielectric material) of the first element A 1304a may be located far from the material (e.g., a support material and / or a dielectric material) of the second element A 1306a. In some examples, the third element A 1344a and the second element A 1306a may be combined on a single printed circuit board. For example, the materials of the third element A 1344a and the second element A 1306a may be combined and / or included within a single printed circuit board. Other elements (e.g., first element A 1304a and second element B 1306, first element B 1304b and second element C 1306c, and / or third element B 1304b and second element D 1306d) may be combined and / or in some examples may be included in one printed circuit board.

[0205] The second elements A-C 1306a-c may be interleaved with the first elements 1304a-b. The first element A 1304a may be larger in size in the x-dimension than the second element A 1306a. The third elements A-B 1344a-b may be larger in size in the x-dimension than the second element A 1306a. The first element A 1304a may be similar in size in the x-dimension to the third element A 1344a.

[0206] Each of the first elements 1304a-b, second elements 1306a-d, and third elements 1344a-b may be disposed on the base 1326. In some examples, each of the first elements 1304a-b, second elements 1306a-d, and / or third elements 1344a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 1326 (e.g., a larger PCB). In some examples, the first elements 1304a-b, second elements 1306a-d, and / or third elements 1344a-b may be implemented within a single PCB that is mounted within the base 1326 (e.g., a larger PCB). In some examples, the antenna 1302 array may be implemented within a single (e.g., monolithic) PCB.

[0207] In some examples, the first elements 1304a-b, the second elements 1306a-d, and / or the third elements 1344a-b may be configured to support bands as described with respect to FIG. 12A, or may be different. In some examples, the element spacing may be implemented as described with respect to FIG. 12A, or may be different. In some examples, the antenna 1302 may support aperture sharing as described with respect to FIG. 12A. In some examples, one or more aspects of the antenna 1302 may be similarly implemented as described with respect to FIG. 12A.

[0208] Figure 14A is a diagram illustrating a top view of another example antenna 1402 according to some of the configurations described herein. Figure 14B is a diagram illustrating an elevation view of the antenna 1402 of Figure 14A. Figures 14A and 14B are described together. The antenna 1402 and / or one or more components of the antenna 1402 may be examples of corresponding components described with respect to Figures 1A and / or 1B. The antenna 1402 shown in Figure 14A is an example of a multi-band dual-polarized shared-aperture interleaved antenna.

[0209] The antenna 1402 may include a first plurality of first elements 1404a-b, a second plurality of second elements 1406a-c, and a third plurality of third elements 1444a-b. In this example, two first elements 1404a-b, three second elements 1406a-c, and two third elements 1444a-b are shown. In this example, the antenna 1402 is 3.5 mm long. In this example, the antenna 1402 is 25 mm wide. In other examples, other dimensions may be used.

[0210] In this example, each of the first elements 1404a-b may include a respective first radiator 1408a-b and second radiator 1418a-b. In this example, the first radiator A 1408a is larger than the second radiator A 1418a in the x and y dimensions. In this example, the first radiator A 1408a is below (e.g., stacked with) the second radiator A 1418a in the z dimension.

[0211] The first radiator A 1408a may be connected and / or coupled to the first feed A 1410a and the second feed A 1414a. The second radiator A 1418a may be connected and / or coupled to the third feed A 1412a and the fourth feed A 1416a. The first element B 1404b may include a respective first radiator B 1408b connected and / or coupled to the respective first feed B 1410b and the respective second feed B 1414b. The first element B 1404b may include a respective second radiator B 1418b connected and / or coupled to the respective third feed B 1412b and the respective fourth feed B 1416b. The first feed A 1410a may correspond to a first polarization, and the second feed A 1414a may correspond to a second polarization. The third feed A 1412a may correspond to a second polarization, and the fourth feed A 1416a may correspond to the first polarization. Each of the first elements 1404a-b may be dual-polarized. In some examples, the first element B 1404b may have an opposed (e.g., mirrored) feed arrangement compared to the first element A 1404a.

[0212] In this example, each of the second elements 1406a-c may include a respective radiator 1420a-c. In this example, the radiator A 1420a of the second element A 1406a may be smaller in size in the x and / or y dimensions than the second radiator A 1442a of the third element A 1444a. The radiator A 1420a of the second element A 1406a may be at a different height than the first radiator A 1408a and / or the second radiator A 1418a of the first element A 1404a.

[0213] Radiator A 1420a may be connected and / or coupled to first feed A 1422a and second feed A 1424a of second element A 1406a. Second elements B-C 1406b-c may each include a respective radiator B-C 1420b-c connected and / or coupled to a respective first feed B-C 1422b-c and a respective second feed B-C 1424b-c. First feed A 1422a of second element A 1406a may correspond to a first polarization, and second feed A 1424a may correspond to a second polarization. Each of second elements 1406a-c may be dual-polarized. Second elements A-C 1406a-c may have similar feed arrangements. In the example of FIG. 14B , each second element 1406a-c shows a dotted line representing a metal dummy between the respective radiator 1420a-c (e.g., a driven patch) and a parasitic radiator (e.g., a parasitic patch). In some examples, the metal dummy may be disposed below the radiator 1420a-c or intermediate the respective radiator 1420a-c and the parasitic radiator without a significant adverse effect on performance. If the metal dummy is disposed beyond the edge of the radiator, the metal dummy may affect performance unless it is spaced far from the edge. In some examples, the metal dummy may cause a loading effect that may lower the radiator operating frequency and / or possibly increase bandwidth. At a sufficient distance from the radiator, the metal dummy may not significantly degrade performance. Although not visible in FIG. 14 , the metal dummy may therefore be disposed near the edge of the PCB. In some examples, each of the metal dummies is sized so as not to radiate a significant amount of energy at the operating frequency of the respective device.

[0214] In this example, each of the third elements 1444a-b may include a respective first radiator 1432a-b and second radiator 1442a-b. In this example, the first radiator A 1432a is larger than the second radiator A 1442a in the x and y dimensions. In this example, the first radiator A 1432a is below (e.g., stacked with) the second radiator A 1442a in the z dimension.

[0215] The first radiator A 1432a may be connected and / or coupled to the first feed A 1434a and the second feed A 1438a. The second radiator A 1442a may be connected and / or coupled to the third feed A 1436a and the fourth feed A 1440a. The third element B 1444b may include a first radiator B 1432b connected and / or coupled to the first feed B 1434b and the second feed B 1438b. The third element B 1444b may include a second radiator B 1442b connected and / or coupled to the third feed B 1436b and the fourth feed B 1440b. The first feed A 1434a may correspond to a first polarization, and the second feed A 1438a may correspond to a second polarization. The third feed A 1436a may correspond to a second polarization, and the fourth feed A 1440a may correspond to a first polarization. Each of the third elements 1444a-b may be dual polarized. In some examples, the third element B 1444b may have an opposed (e.g., mirrored) feed arrangement compared to the third element A 1444a.

[0216] The first element A 1404a may include a first radiator A 1408a and / or a second radiator A 1418a embedded in a material (e.g., a support material and / or a dielectric material). In some examples, two or more elements may be combined or separated on a printed circuit board. For example, the material (e.g., a support material and / or a dielectric material) of the first element A 1404a may be located far from the material (e.g., a support material and / or a dielectric material) of the second element A 1406a. In some examples, the third element A 1444a and the second element A 1406a may be combined on a single printed circuit board. For example, the materials of the third element A 1444a and the second element A 1406a may be combined and / or included within a single printed circuit board. Other elements (e.g., first element A 1404a and second element B 1406, and / or first element B 1404b and second element C 1406c) may be combined and / or in some examples may be included in one printed circuit board.

[0217] The second elements A-C 1406a-c may be interleaved with the first elements 1404a-b. The first element A 1404a may be larger in size in the x-dimension than the second element A 1406a. The third elements A-B 1444a-b may be larger in size in the x-dimension than the second element A 1406a. The first element A 1404a may be similar in size in the x-dimension to the third element A 1444a.

[0218] Each of the first elements 1404a-b, second elements 1406a-c, and third elements 1444a-b may be disposed on the base 1426. In some examples, each of the first elements 1404a-b, second elements 1406a-c, and / or third elements 1444a-b may be implemented as and / or included within a respective PCB that is assembled, soldered, and / or surface mounted on the base 1426 (e.g., a larger PCB). In some examples, the first elements 1404a-b, second elements 1406a-c, and / or third elements 1444a-b may be implemented within a single PCB that is mounted within the base 1426 (e.g., a larger PCB). In some examples, the antenna 1402 array may be implemented within a single (e.g., monolithic) PCB.

[0219] In some configurations, each of the first elements 1404a-b may be configured to support a first set of bands and a second set of bands. In this example, the first set of bands includes the 24.25-27.5 GHz band (e.g., n258), the 26.5-29.5 GHz band (e.g., n257), and / or the 27.5-28.35 GHz band (e.g., n261). In this example, the second set of bands includes the 37-40 GHz band (e.g., n260) and / or the 39.5-43.5 GHz band (e.g., n259). In some examples, the second elements 1406a-c and / or the third elements 1444a-b may support the 47.2-48.2 GHz band (e.g., the 48 GHz band, n262). In some examples, one or more third bands may be supported by one or more third elements (e.g., third elements 1444a-b). For example, the third band may include the 47.2-48.2 GHz band (e.g., the 48 GHz band, n262). In some examples, the third elements 1444a-b may support a first set of bands. In this example, the second set of bands may be mutually exclusive from the first set of bands. In this example, the first set of bands are lower in frequency than the second set of bands.

[0220] In some configurations, each of the second elements 1406a-c may be configured to support a second set of bands. For example, each of the second elements 1406a-c may support a second set of bands that are also supported by the first elements 1404a-b. In some examples, each of the second elements 1406a-c may not support the first set of bands (e.g., may not transmit signals in the first set of bands and / or may not be utilized to receive signals in the first set of bands). In some examples, the number of elements for the first set of bands (e.g., four) may be different from the number of elements for the second set of bands and / or the third band (e.g., five). For example, the antenna 1402 may provide a 1 x 4 element array for the first set of bands, a 1 x 5 element array for the second set of bands, and a 1 x 5 array for the third (e.g., 48G) band.

[0221] In this example, the first element spacing 1428 (e.g., 6.6 mm) for the first set of bands may be larger than the second element spacing 1430 (e.g., 3.3 mm) for the third band (e.g., 48 G). For example, the first set of bands may be supported by the first elements 1404a-b and not by the second set of elements 1406a-c. Thus, the first element spacing 1428 for the first set of bands may be the distance between the center of the third element A 1444a and the center of the first element A 1404a, and / or the distance between the center of the first element A 1404a and the center of the first element B 1404b. The first element spacing 1428 may range from approximately 0.53 to 0.65λ for the first set of bands, where λ is the signal wavelength. A second set of bands may be supported by each of the first elements 1404a-b and the second elements 1406a-c. A second element spacing 1430 for a third band (e.g., 48G) may be the distance between the center of the third element A 1444a and the center of the second element A 1406a. The second element spacing 1430 may be approximately 0.53λ for the 48G band. In this example, a third element spacing 1448 (e.g., 6.6 mm) may be used for the 48G band between the centers of the second elements 1406a-c. The third element spacing 1448 may be approximately 1.06λ for the 48G band. In this example, first elements 1404a-b (for the first set of bands and the second set of bands), second elements 1406a-c (for the second set of bands and / or the third band (e.g., 48G)), and third elements 1444a-b (for the first set of bands and the third band) may support multiple bands through aperture sharing.

[0222] In some examples, the third element A 1444a includes a first radiator A 1432a below the second radiator A 1442a but not the radiator A 1420a of the second element A 1406a, so the second radiator A 1442a of the third element A 1444a may be larger than the radiator A 1420a of the second element A 1406a. For example, the first radiator A 1432a (e.g., a low-band patch) of the third element A 1444a may serve as a ground plane for the second radiator A 1442a (e.g., a high-band patch). A radiator (e.g., a patch) closer to the ground plane may be larger than a radiator (e.g., a patch) farther away from the ground plane to radiate at the same frequency. In the example shown in FIG. 14B, the elements are equal or approximately equal in height. In some instances, elements that are combined on a PCB may be equal or approximately equal in height.

[0223] FIG. 15 is a diagram illustrating an elevation view of another example of an antenna 1502 according to some of the configurations described herein. The antenna 1502 and / or one or more components of the antenna 1502 may be examples of corresponding components described with respect to FIGS. 1A and / or 1B. The antenna 1502 shown in FIG. 15 is an example of a multi-band, dual-polarized, shared-aperture, interleaved antenna. FIG. 15 illustrates an alternative configuration of the antenna 1402 described with respect to FIG. 14A. For example, the components described with respect to FIG. 14A may be similar to the corresponding components described with respect to FIG. 15. However, the components described in FIG. 15 may vary in one or more aspects compared to the components described with respect to FIG. 14B. For example, some of the components of FIG. 15 may vary with respect to the z (e.g., height) dimension.

[0224] 15, the elements may have different heights. For example, the second elements 1506a-c have a smaller height compared to the third elements 1544a-b and / or the first elements 1504a-b.
