Figures 6 to 13 This is a diagram illustrating an antenna according to an embodiment of the present disclosure.

[0037] Antenna 100 according to one embodiment of the present disclosure may include a first radiating patch 110 and a second radiating patch 120. Antenna according to embodiments of the present disclosure may be an antenna radiating signals across multiple frequency bands. For example, the antenna may be capable of transmitting and receiving signals including all 5G millimeter-wave (mmWave) bands n257, n258, n259, n260, and n261. Antenna 100 may be an antenna used in mobile devices, base stations, repeaters, etc., and may perform near-field high-speed broadband communication for mobile devices and mobile terminals.

[0038] An antenna device according to an embodiment of the present disclosure may include an antenna 100. Here, the antenna substrate may refer to a hybrid antenna substrate, an antenna in-package (AIP), an antenna array substrate, or an antenna array.

[0039] The antenna substrate may include antenna elements and wiring elements, wherein the antenna elements include an antenna. In one embodiment, the antenna elements may be disposed above the wiring elements. In one embodiment, the antenna substrate may further include a core element, wherein the antenna elements are disposed above the core element and the wiring elements are disposed below the core element. In one embodiment, the antenna elements and wiring elements may be disposed on the same horizontal plane. In one embodiment, the wiring elements and antenna elements may be spaced apart from each other, and the wiring elements and antenna elements may be electrically connected to each other by connecting members, such as flexible printed circuit boards (FPCBs), solder balls, or metal bumps. For ease of description, it is assumed below that the antenna elements of the antenna substrate are disposed above the wiring elements; however, this disclosure also applies to cases where the antenna substrate has the structure of the above embodiments.

[0040] The antenna substrate may include a plurality of wiring layers and a plurality of insulating layers stacked and spaced apart from each other in a vertical direction. In one embodiment, an antenna element may include a plurality of first wiring layers and a plurality of first insulating layers. The wiring element may include a plurality of second wiring layers disposed below the plurality of first wiring layers and a plurality of second insulating layers disposed below the plurality of first insulating layers.

[0041] Here, the wiring layer may include radiating patches, stubs, feed pads, feed sections, grounding, and transmission lines that constitute the antenna. Current supplied through the ports can be supplied to the antenna elements through the transmission lines. The wiring layer may contain metallic materials such as copper (Cu), aluminum (Al), silver (Ag), tin (Sn), gold (Au), nickel (Ni), lead (Pb), titanium (Ti), or alloys thereof.

[0042] Here, the first and second insulating layers may each comprise a material such as a thermosetting resin (such as epoxy resin), a thermoplastic resin (such as polyimide), or a reinforcing material (such as glass fiber and / or inorganic filler) in combination with these materials, for example ABF, PID, BCC, or prepreg (PPG). Furthermore, each of the first and second insulating layers may comprise a glass plate or a ceramic plate.

[0043] The wiring layers included in a wiring unit may include signal patterns, power patterns, or resistor patterns. In addition, the wiring unit may have a variety of complex wiring characteristics, such as power / data wiring, input / output wiring, and radio frequency (RF) wiring.

[0044] The second radiating patch 120 has an aperture 130 formed therein corresponding to the shape of the first radiating patch 110, and the first radiating patch 110 is disposed in the aperture 130 of the second radiating patch 120. The first radiating patch 110 may be quadrilateral in shape, and the aperture 130 of the second radiating patch 120 may be formed as a quadrilateral corresponding to the quadrilateral shape of the first radiating patch 110. The quadrilateral shape is used for simplification of the description of the radiating patch, and it should be understood that the shape can naturally have various shapes such as circular, elliptical, or including slits or slots.

[0045] The first radiating patch 110 and the second radiating patch 120 can be arranged spaced apart from each other. The area of ​​the aperture 130 of the second radiating patch 120 can be larger than the area of ​​the first radiating patch 110. The area of ​​the first radiating patch 110 can be smaller than the area of ​​the aperture 130 of the second radiating patch 120, such that the first radiating patch 110 can be disposed inside the aperture 130 of the second radiating patch 120. In this case, the first radiating patch 110 can be spaced apart from the second radiating patch 120. The outer side of the first radiating patch 110 and the inner side of the second radiating patch 120 can be spaced apart from each other. At this time, the distances from all surfaces of the first radiating patch 110 to the second radiating patch 120 can be set to be equidistantly spaced. When the first radiating patch 110 and the second radiating patch 120 are circular or elliptical, the distances from all points to the second radiating patch 120 can be uniformly spaced. However, this disclosure is not limited to the above description, and the distance to the second radiating patch 120 may be equidistant on at least a portion of all surfaces (or points) of the first radiating patch 110.

[0046] The first radiating patch 110 and the second radiating patch 120 can be disposed on the same plane. The first radiating patch 110 and the second radiating patch 120 are concentric and can be disposed on the same plane. That is, the first radiating patch 110 and the second radiating patch 120 can be formed on the same layer, and the two radiating patches can be formed on a single layer, thereby reducing the required number of layers or the overall size of the antenna.

[0047] The frequency of the radiated signal from the first radiating patch 110 may differ from the frequency of the radiated signal from the second radiating patch 120. Here, the frequency of the radiated signal from the first radiating patch 110 may be higher than the frequency of the radiated signal from the second radiating patch 120. Alternatively, the frequency of the radiated signal from the second radiating patch 120 may be higher than the frequency of the radiated signal from the first radiating patch 110. The frequency band of the radiated signal from the first radiating patch 110 may differ from the frequency band of the radiated signal from the second radiating patch 120. The frequency band of the radiated signal from the first radiating patch 110 may be relatively lower than the frequency band of the second radiating patch 120. The frequency band of the radiated signal from the first radiating patch 110 may be a low-frequency band (LB), and the frequency band of the radiated signal from the second radiating patch 120 may be a high-frequency band (HB). For example, the frequency band of the radiated signal from the first radiating patch 110 may be a low-frequency range of 24.25 to 29.5 GHz, and the radiated signal from the second radiating patch 120 may radiate a signal in a high-frequency range of 37.0 to 43.5 GHz.

[0048] The first radiating patch 110 and the second radiating patch 120 can be arranged on the same plane and spaced apart from each other, thereby forming a slot in the space 130 between the first radiating patch 110 and the second radiating patch 120. Here, the slot is formed as a closed slot structure and can form a filter. The slot can form a band-stop filter. This reduces the interference between the radiated signals of the first radiating patch 110 and the second radiating patch 120, thereby improving isolation and impedance. The first radiating patch 110 and the second radiating patch 120 can be arranged on the same plane, for clarity, in Figure 2 , Figure 3 and Figure 6 The second radiating patch 120 is omitted; however, it should be understood that in Figure 2 , Figure 3 and Figure 6 The first radiating patch 110 and the second radiating patch 120 are set in the middle.

[0049] The first radiating patch 110 and the second radiating patch 120 can be spaced apart and form a coupling between the first radiating patch 110 and the second radiating patch 120, which can be used for the design of the radiated signals of the first radiating patch 110 and the second radiating patch 120.

[0050] On the same plane, the first radiating patch 110, the second radiating patch 120, and the first radiating patch 110 and the second radiating patch 120 form a filter according to the spacing space 130, and therefore can be called a mixed mode patch.

[0051] The lower portion of the first radiating patch 110 may include a quadrilateral third radiating patch 140, which is configured to be spaced apart from the first radiating patch 110. For example... Figure 2 and Figure 3 As shown, the first radiating patch 110 and the third radiating patch 140 are arranged spaced apart from each other, and when the third radiating patch 140 is driven, the first radiating patch 110 is also driven. The third radiating patch 140 may be a high-frequency driving patch (HB driving patch), and the first radiating patch 110 may be a high-frequency stacked patch (HB stacked patch) that forms a stacked structure with the third radiating patch 140.

[0052] The first radiating patch 110 and the third radiating patch 140 can be formed into a quadrilateral shape, and the first radiating patch 110 and the third radiating patch 140 can be set at a 45-degree angle to each other. For example... Figure 3As shown, the first radiating patch 110 can be configured to rotate 45 degrees relative to the third radiating patch 140. The second radiating patch 120 can also be configured to rotate 45 degrees relative to the third radiating patch 140. In this case, the angular difference between the first radiating patch 110 and the third radiating patch 140 can refer to the angle formed between a surface of the first radiating patch 110 and a surface of the third radiating patch 140. On the other hand, although... Figure 3 The first radiating patch 110 and the third radiating patch 140 are shown and described as having a 45-degree difference, but this disclosure is not limited thereto. For example, the first radiating patch 110 and the third radiating patch 140 may be configured to have an acute angle or a right angle difference. Furthermore, according to an embodiment, the first radiating patch 110 and the third radiating patch 140 may be configured at the same angle.

[0053] The third radiating patch 140 can be formed in a quadrilateral shape, or it may include recesses 141 in which the corners of the quadrilateral shape are recessed inward. The recesses 141 can be designed to have a frequency of the radiated signal to be radiated through the recesses 141 by being recessed towards the inward side of the corners. The third radiating patch 140 can be as follows: Figure 4 The shape shown is formed as follows: the quadrilateral shape is formed with corners formed as curves, and the shape can be formed into a rectangular shape by the shape of the patch extending from each of the four sides. The shape of the recess 141 can be formed to correspond to the shape formed by the corners formed as curves and the rectangular shape extending from the four sides.

[0054] The main radiating patch, including the first radiating patch 110 and the second radiating patch 120, may include multiple main radiating patches, and two adjacent main radiating patches may be arranged in a manner that rotates around their center so that their corners face each other. Furthermore, the multiple main radiating patches may be spaced apart and arranged horizontally.

[0055] The third radiating patch 140 may include a power feed pad 150, which is spaced apart from the lower portion of the third radiating patch 140. The power feed pad 150 can provide power to the third radiating patch 140. In this case, the power feed pad 150 can indirectly power the third radiating patch 140. That is, the power feed pad 150 may not be electrically connected to the third radiating patch 140 and can be powered by coupling.

[0056] The power feed pad 150 may have a tapered shape 153 in a region near the center of the third radiating patch 140. The power feed pad 150 may include two power feed pads 151 and 152 disposed at positions corresponding to the corners of the third radiating patch 140. For example... Figure 5 As shown, the power supply pad 150 may include two power supply pads 151 and 152, and as... Figure 3 As shown, it can be positioned at a location corresponding to the corner of the third radiating patch 140. The two feed pads 151 and 152 can be spaced apart from each other and extend in a direction toward the center of the third radiating patch 140. The tapered shape 153 formed in the region near the center of the third radiating patch 140 can be designed to have the same frequency as the signal to be radiated from the third radiating patch 140 when power is supplied to it.

[0057] The power feed pad 150 may include a via structure and can be electrically connected to a transmission line via a power feed section connected to the lower part, such as... Figure 3 As shown. Current flows through the feed pads 150 via the feed sections 171 and 172 connected to the transmission line, thereby feeding the feed pads 150 and enabling them to feed the third radiating patch 140.

[0058] The third radiating patch 140 can be coupled and fed once via the feed pad 150, and when the third radiating patch 140 is fed, the first radiating patch 110 can be coupled and fed a second time via the third radiating patch 140. Alternatively, the third radiating patch 140 and the first radiating patch 110 can be coupled and fed simultaneously via the feed pad 150.

[0059] The third radiating patch 140 and the first radiating patch 110 can radiate signals in a dual-polarization mode, i.e., H-pole and V-pole. Here, H represents horizontal and V represents vertical. The two feed pads 151 and 152 can each include an H-pole feed pad and a V-pole feed pad. When fed through the H-pole feed pad, the third radiating patch 140 or the first radiating patch 110 radiates signals with H-pole polarization, and when fed through the V-pole feed pad, the third radiating patch 140 or the first radiating patch 110 can radiate signals with V-pole polarization. Furthermore, when fed through both the H-pole and V-pole feed pads, the third radiating patch 140 or the first radiating patch 110 can radiate signals with both H-pole and V-pole dual polarization.

[0060] The second radiating patch 120 can be directly connected to the feed unit. Unlike the third radiating patch 140 or the first radiating patch 110, which are indirectly fed, the second radiating patch 120 can be directly fed through the feed unit. The second radiating patch 120 can radiate signals with dual polarization (H-pole and V-pole). In this case, the second radiating patch 120 can be fed through both the H-pole feed unit and the V-pole feed unit. When fed (powered) through the H-pole feed unit, the second radiating patch 120 radiates signals with H-pole polarization, and when fed through the V-pole feed unit, the second radiating patch 120 can radiate signals with V-pole polarization. Furthermore, when fed through both the H-pole feed unit and the V-pole feed unit, the second radiating patch 120 can radiate signals with dual polarization (H-pole and V-pole).

[0061] The antenna 100 according to embodiments of the present disclosure may be composed of multiple layers. The antenna 100 according to embodiments of the present disclosure may include multiple insulating layers, and radiating patches or feed patches may be disposed on each layer, and the layers may be electrically connected through vias. The radiating patches or feed patches may be formed of a metallic material or may be composed of other conductive materials. Figure 6 As shown, the antenna can be configured as a multi-layer structure including a first radiating patch 110, a second radiating patch 120, a third radiating patch 140, and a feed pad 150. The top layer may include the first radiating patch 110 and the second radiating patch 120 arranged as a single layer of main radiating patches. The next layer may include a stub 160. Here, the stub 160 may be as follows: Figure 7 The configuration is shown and can be a parasitic stub. The next layer may include a third radiating patch 140 spaced apart from the first radiating patch 110, and subsequent layers may include feed pads 150. Feed pads 150 may indirectly feed (power) the third radiating patch 140 or the first radiating patch 110. Feed pads 150 can be connected to transmission lines via feed sections. Here, feed pads 150 may include H-pole feed pads and V-pole feed pads, and each feed pad can be connected to its respective feed sections 171 and 172. The second radiating patch 120 can be directly connected to the H-pole feed section 181 and the V-pole feed section 182, which include vias. The first radiating patch 110 and the third radiating patch 140 can be connected to ground via a central via 180 to improve isolation.

[0062] The isolation between signals emitted from the first radiating patch 110 and the second radiating patch 120 can be set according to the length and spacing of each component, including but not limited to the spacing a between the first radiating patch 110 and the second radiating patch 120, the length b of one side of the first radiating patch 110, the length c of one side of the second radiating patch 120, the length d of one side of the third radiating patch 140, the lengths e and f of the feed pad 150, and the lengths g and h of the stub 160, etc. The impedance and isolation of the low-frequency and high-frequency bands can be improved according to the spacing a between the first radiating patch 110 and the second radiating patch 120, the impedance, bandwidth, and performance of the high-frequency band can be improved according to the length b of one side of the first radiating patch 110, and the coupling with the first radiating patch 110 can be designed according to the length c of one side of the second radiating patch 120.

[0063] Figure 9 This is a graph showing the isolation between the low-frequency and high-frequency bands. It can be seen that the isolation has been improved in the high-frequency band region. Figure 10 The graph shows the isolation between the H and V poles in the high-frequency band, and it can be seen that the isolation between the H and V poles has also been improved. Figure 11 The S-parameters for the high-frequency band are shown, where the light-colored lines represent the initial values ​​before applying the hybrid structure of this disclosure, and the dark-colored lines represent the results after applying the hybrid structure of this disclosure, confirming the improvement in signal performance in the high-frequency band. Figure 12 The S-parameters for the low-frequency band are shown, where the light-colored lines represent the initial values ​​before applying the hybrid structure of this disclosure, and the dark-colored lines represent the results after applying the hybrid structure of this disclosure. This confirms that signal performance has also been improved in the low-frequency band.

[0064] Figure 13 A signal according to one embodiment of this disclosure is shown. For example, a signal is shown when a=0.15, b=1.44, c=2.44, d=1.34, e=0.58, f=2.7, g=2.3, h=0.35 (mm), and it can be confirmed that the isolation has been improved in both the low-frequency range of 24.25 to 29.5 GHz and the high-frequency range of 37.0 to 43.5 GHz.
