Description

Antennas, antenna arrays and electronic equipment Technical Field

[0001] The present disclosure belongs to the field of communication technology, and particularly relates to an antenna, an antenna array, and an electronic device. Background Art

[0002] As an important component of the antenna, the phase shifter can be regarded as a delay line. If an adjustable dielectric material is used instead of the traditional solid substrate, a phase-variable phase shifter can be obtained. Liquid crystal is used as a tunable dielectric material here. The liquid crystal phase shifter is a phase-variable phase shifter. By applying voltage to the upper and lower substrates of the liquid crystal phase shifter to form an overlapping capacitor, the dielectric constant of the liquid crystal material is changed, which changes the phase constant of the electromagnetic wave on the device, ultimately achieving the effect of adjusting the phase shift amount, thereby realizing the wave number scanning function of the antenna device. Currently, common liquid crystal antennas are only single-polarized, while the design of dual-polarized antennas is very complex, and the layout of the phase shifter unit and the wiring must be considered. Therefore, providing a simple and easy-to-implement dual-polarized antenna is a technical problem that needs to be solved urgently.

[0072] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0073] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0074] A balun (balun-unbalance) component is a three-port device that can be used in microwave RF devices. A balun component is an RF transmission line transformer that converts a matched input into a differential input. It can be used to excite differential lines, amplifiers, broadband antennas, balanced mixers, balanced frequency multipliers and modulators, phase shifters, and any circuit design that requires transmitting equal amplitudes and a 180° phase difference on two lines. The two outputs of a balun component have equal amplitudes and opposite phases. In the frequency domain, this means there is a 180° phase difference between the two outputs; in the time domain, this means the voltage of one balanced output is the negative of the other balanced output.

[0075] Figure 1 is a schematic diagram of an exemplary liquid crystal phase shifter. As shown in Figure 1 , the key feature of a differential liquid crystal phase shifter is that it operates in differential mode, resulting in higher phase shifting efficiency compared to single-line phase shifters. However, to provide differential-mode signals, a balun component 201 and a balun component 202 are required at the input and output of phase shifter 111, respectively, to achieve unbalanced-balanced-unbalanced signal conversion.

[0076] The phase shifter typically includes a first electrode layer disposed on the side of a first dielectric substrate closest to a second dielectric substrate, a second electrode layer disposed on the side of the second dielectric substrate closest to the first dielectric substrate, and an adjustable dielectric layer located between the first and second electrode layers. In a liquid crystal phase shifter, the adjustable dielectric layer is a liquid crystal layer. The following describes two examples of differential liquid crystal phase shifters formed with different first and second electrode layers.

[0077] Example 1: Figure 2 is a partial schematic diagram of the first exemplary differential phase shifter; Figure 3 is a cross-sectional view taken along line AA' of Figure 2 . As shown in Figures 2 and 3 , the phase shifter's first electrode layer 111a includes a first transmission line 1111 and a second transmission line 1112 extending in the same direction. The second electrode layer 111b includes a plurality of patch electrodes 2112 arranged side by side along the direction of the first transmission line 1111. The first and second transmission lines 1111 and 1112 overlap with their orthographic projections onto the first dielectric substrate 10. In this case, the liquid crystal layer is located between the first and second transmission lines 1111 and 1112. The first transmission line 1111 and the second transmission line 1112 respectively form a capacitor area at the overlapping area with the patch electrode 2112. By loading different voltages on the first transmission line 1111, the second transmission line 1112 and the patch electrode 2112, an electric field is formed in the overlapping area of ​​the first transmission line 1111 and the patch electrode 2112, and an electric field is also formed in the overlapping area of ​​the second transmission line 1112 and the patch electrode 2112, so that the dielectric constant of the liquid crystal molecules in the liquid crystal layer 111c in the overlapping area of ​​the first transmission line 1111 and the patch electrode 2112 and the overlapping area of ​​the second transmission line 1112 and the patch electrode 2112 changes, thereby achieving phase shift of the microwave signal.

[0078] Second Example: Figure 4 is a partial schematic diagram of a second exemplary differential phase shifter; Figure 5 is a cross-sectional view taken along line BB' of Figure 4 . As shown in Figures 4 and 5 , the first electrode layer 111a of the phase shifter includes a first transmission line 1111, and the second electrode layer 111b includes a second transmission line 1112. The first transmission line 1111 includes a first main line 1111a and a first branch 1111b, while the second transmission line 1112 includes a second main line 2111a and a second branch 2111b. The first branch 1111b connects to one side of the first main line 1111a in the direction of its extension, and both the first main line 1111a and the first branch 1111b are disposed on the side of the first dielectric substrate 10 closest to the liquid crystal layer. The second branch 2111b connects to one side of the second main line 2111a in the direction of its extension, and both the second main line 2111a and the second branch 2111b are disposed on the side of the second dielectric substrate 20 closest to the liquid crystal layer. The orthographic projections of a first branch portion 1111b and a second branch portion 2111b on the first dielectric substrate 10 at least partially overlap, defining an overlapping region (i.e., a capacitor region). The overlapping region is located between the orthographic projections of the first main line 1111a and the second main line 2111a on the first dielectric substrate 10. By applying a bias voltage to the first main line 1111a and the second main line 2111a, an electric field is formed in the capacitor region, which changes the dielectric constant of the liquid crystal molecules, thereby achieving phase shifting of the microwave signal.

[0079] In existing dual-polarization antennas, two phase shifters are required to adjust the phase of the electromagnetic waves fed into the radiating structure respectively. Due to limited space, setting up a phase shifter using a balun structure will inevitably cause problems such as space limitations. In order to provide the following technical solutions in the embodiments of the present disclosure.

[0080] It should be noted that the first phase adjustment structure 11 and the second phase adjustment structure 21 in the following embodiments of the present disclosure include but are not limited to the above-mentioned liquid crystal phase shifter, and in the embodiments of the present disclosure, only the phase shifter is used as an example for description, that is, the first adjustable electrode layer 111c of the first phase adjustment structure 11 and the first adjustable electrode layer 211c of the phase adjustment structure 21 as shown in the figure are both liquid crystal layers.

[0081] Figure 6 is a top view of the antenna of an embodiment of the present disclosure; Figure 7 is a schematic diagram of the relative position relationship of the first opening 501, the second opening 502, the first feed line 112, and the second feed line 212 in the antenna of an embodiment of the present disclosure; as shown in Figures 6 and 7, an embodiment of the present disclosure provides an antenna, which is a dual-polarization antenna, a first phase adjustment structure 11, a second phase adjustment structure 21, a first feed line 112, a second feed line 212 and a first radiation structure 12. The first phase adjustment structure 11 includes a first transmission line 1111 and a second transmission line 1112, and the second phase adjustment structure 21 includes a third transmission line and a fourth transmission line. The first feeder 112 and the second feeder 212 each have a first end and a second end, which are P11, P12, P21, and P22, respectively. The first end P11 of the first feeder 112 is electrically connected to the first transmission line 1111, and the second end P12 of the first feeder 112 is electrically connected to the second transmission line 1112. The first end P21 of the second feeder 212 is electrically connected to the third transmission line, and the second end P22 of the second feeder 212 is electrically connected to the fourth transmission line. The first feeder 112 and the second feeder 212 are both electrically connected to the first radiating structure 12, and the feeding directions of the first feeder 112 and the second feeder 212 are different. In the embodiment of the present disclosure, the feeding directions of the first feeder 112 and the second feeder 212 are two mutually perpendicular directions.

[0082] Specifically, the antenna includes not only the first phase adjustment structure 11, the second phase adjustment structure 21, the first feed line 112, the second feed line 212, and the first radiating structure 12 described above, but also includes a first dielectric substrate 10, a second dielectric substrate 20, and a first reference electrode layer 50. The first reference electrode layer 50 has a first opening 501 and a second opening 502, and the first reference electrode is arranged on a side of the second dielectric substrate 20 facing away from the first dielectric substrate 10. The first feed line 112 is coupled to the first radiating structure 12 through the first opening 501, and the second feed line 212 is coupled to the first radiating structure 12 through the second opening 502.

[0083] In the embodiment of the present disclosure, both ends of the first feeder 112 are electrically connected to the first transmission line 1111 and the second transmission line 1112, respectively, to form a ring feeder. Both ends of the second feeder 212 are electrically connected to the third transmission line and the fourth transmission line, respectively, to form a ring feeder. For the feeding point of the radiating structure of the ring feeder, the electromagnetic wave signal is divided into two paths of equal amplitude and anti-phase. Therefore, by reasonably designing the line lengths of the two transmission paths, the electromagnetic wave signals at the first end and the second end of the first feeder 112 can be equal amplitude and anti-phase. Similarly, the electromagnetic wave signals at the first end and the second end of the second feeder 212 can be equal amplitude and anti-phase. Therefore, the arrangement of the transmission components (such as baluns) in the first phase adjustment structure 11 and the second phase adjustment structure 21 can be omitted, which is more convenient for arranging the various components in the antenna.

[0084] In some examples, the feeding point through which the first feeder 112 feeds the first radiating structure 12 is the first feeding point E1, and the feeding point through which the second feeder 212 feeds the first radiating structure 12 is the second feeding point E2. The first feeding point E1 divides the first feeder 112 into a first sub-feeder 112a and a second sub-feeder 112a, and the second feeding point E2 divides the second feeder 212 into a third sub-feeder 212a and a fourth sub-feeder 212b. The first sub-feeder 112a and the second sub-feeder 112a have equal lengths, and the third sub-feeder 212a and the fourth sub-feeder 212b have equal lengths. In this case, the electromagnetic wave signals at the first and second ends of the first feeder 112 are equal in amplitude and anti-phase, and the electromagnetic wave signals at the first and second ends of the second feeder 212 are equal in amplitude and anti-phase.

[0085] Furthermore, in order to reduce the size, a winding design can be performed on the first feeder 112 and the second feeder 212. For example, at least one of the first sub-feeder 112a and the second sub-feeder 112a of the first feeder 112 includes a meandering line; and / or at least one of the third sub-feeder 212a and the fourth sub-feeder 212b of the second feeder 212 includes a meandering line.

[0086] Furthermore, in order to reduce the size, the first feeder 112 and the second feeder 212 may be arranged in a mirror-symmetrical manner.

[0087] The antenna in the embodiments of the present disclosure may be any one of a reflective antenna, a transmissive antenna, and a phased array antenna. The following describes these three types of antennas in detail.

[0088] Example 1: Figure 8 is a cross-sectional view of an antenna according to the first example of the present embodiment. As shown in Figures 6-8, this antenna is a reflective antenna. It includes not only the first phase adjustment structure 11, the second phase adjustment structure 21, the first feed line 112, the second feed line 212, and the first radiating structure 12 described above, but also a first dielectric substrate 10, a second dielectric substrate 20, a first reference electrode layer 50, and a second reference electrode layer 60. The first phase adjustment structure 11 and the second phase adjustment structure 21 are integrated between the first dielectric substrate 10 and the second dielectric substrate 20. The first reference electrode layer 50 has a first opening 501 and a second opening 502. The first reference electrode is disposed on the side of the second dielectric substrate 20 facing away from the first dielectric substrate 10. The first feed line 112 is coupled to the first radiating structure 12 through the first opening 501, and the second feed line 212 is coupled to the first radiating structure 12 through the second opening 502. The second reference electrode is disposed on the side of the second dielectric substrate 20 facing away from the first dielectric layer, serving as a reflective layer. In this case, after receiving the electromagnetic wave, the first radiating structure 12 transmits the electromagnetic wave to the first feeder 112 and the second feeder 212 through the first opening 501 on the first reference electrical layer. The first feeder 112 transmits the electromagnetic wave to the first phase adjustment structure 11. Then the first phase adjustment structure 11 performs phase shift modulation on the electromagnetic wave and transmits it to the reflective layer. The reflective layer reflects the electromagnetic wave to the first radiating structure 12. The second feeder 212 transmits the electromagnetic wave to the second phase adjustment structure 21. Then the second phase adjustment structure 21 performs phase shift modulation on the electromagnetic wave and transmits it to the reflective layer. The reflective layer reflects the electromagnetic wave to the first radiating structure 12. The two magnetic waves are combined and radiated through the first radiating structure 12.

[0089] Furthermore, the reflective antenna may also include a third dielectric substrate 30 and a fourth dielectric substrate 40. The third dielectric substrate 30 is disposed on a side of the first reference electrode layer 50 facing away from the second dielectric substrate 20, and the fourth dielectric substrate 40 is disposed on a side of the second reference electrode layer 60 facing away from the first dielectric substrate 10. In this case, the first radiating structure 12 may be disposed on the third dielectric substrate 30, for example, on a side of the third dielectric substrate 30 facing away from the second dielectric substrate 20. The second reference electrode layer 60 may be formed on the fourth dielectric substrate 40 and then bonded to the first dielectric substrate 10.

[0090] In some examples, FIG9 is a schematic diagram of the first opening 501 and the second opening 502 of the embodiment of the present disclosure; as shown in FIG9 , the shape of the first opening 501 and the second opening 502 can be any shape such as U-shaped, straight, H-shaped, open loop, etc. Further, when the first opening 501 and the second opening 502 are straight openings, the width of the middle area is not greater than the width of the two sides, for example: the sides of the first opening 501 and the second opening 502 along their respective extension directions can be arcs or broken lines. In the embodiment of the present disclosure, only the first opening 501 and the second opening 502 are U-shaped openings as an example. In some examples, the first opening 501 and the second opening 502 in the first reference electrode layer 50 are arranged in mirror symmetry. At least part of the structure of the first feed line 112 and the second feed line 212 is located between the areas defined by the first opening 501 and the second opening 502. For example, the orthographic projections of the second sub-feeder 112 a of the first feeder 112 and the fourth sub-feeder 212 b of the second feeder 212 on the first dielectric substrate 10 are located between the orthographic projections of the first opening 501 and the second opening 502 on the first dielectric substrate 10 .

[0091] Continuing with Figure 8 , the first feeder 112 and the second feeder 212 can be arranged in mirror-image symmetry, meaning that the first feeder 112 and the second feeder 212 have the same winding configuration. The relative positional relationship between the first feeder 112 and the first opening 501 is the same as the relative positional relationship between the second feeder 212 and the second opening 502. The following description will only use the relative positional relationship between the first feeder 112 and the second opening 502 as an example. The intersection of the orthographic projections of the first feeder 112 and the first opening 501 on the first dielectric substrate 10 is the orthographic projection of the first feeding point E1 of the first feeder 112 on the first dielectric substrate 10. The first opening 501 includes a first sub-opening, a second sub-opening connected to both ends of the first sub-opening, and a third sub-opening. The orthographic projection of the first feeding point E1 on the first dielectric substrate 10 coincides with the midpoint of the first sub-opening on the first dielectric substrate 10. The second sub-opening and the third sub-opening are arranged symmetrically about a line passing through the first feeding point E1 and perpendicular to the first sub-opening. Except for the first feeding point E1, the remaining locations of the first feeder 112 should ensure a certain distance from the first opening 501 to avoid signal coupling. As can be seen from Figure 7, points C and D on the first opening 501 are closer to the first feeder 112, so the distance between these two locations needs to be reasonably set. Figure 10 is a schematic diagram of the winding of the first feeder 112 and the second feeder 212 in an embodiment of the present disclosure. As shown in Figure 10, the winding method of the first feeder 112 and the second feeder 212 is not limited to the one shown in Figure 7.

[0092] In some examples, Figure 11 is a schematic diagram of the relative positions of the first phase adjustment structure 11 and the second phase adjustment structure 21 of an embodiment of the present disclosure; as shown in Figure 11, the first phase adjustment structure 11 and the second phase adjustment structure 21 can be set in any manner, such as horizontal, vertical, relative tilt, etc. By reasonably setting the first phase adjustment structure 11 and the second phase adjustment structure 21, two phase adjustment structures can be set in one antenna, and at the same time, the interface can be clear and feeding can be easily achieved.

[0093] In some examples, Figure 12 is a schematic diagram of the relative position relationship of another first opening 501, the second opening 502, the first feed line 112, and the second feed line 212 of an embodiment of the present disclosure; as shown in Figure 12, the antenna of the embodiment of the present disclosure can have multiple polarization forms, which can be but not limited to horizontal polarization, vertical polarization, various circular polarizations, etc., and its first feed line 112 and the second feed line 212 and the first radiation structure 12 can be rotated and adjusted accordingly.

[0094] In some examples, the first electrode layer 111a in the first phase adjustment structure 11 is biased by a first bias voltage line 114, and the second electrode layer 111b is biased by a second bias voltage line 115. The first bias voltage line 114 can be disposed on a side of the first electrode layer 111a close to the first dielectric substrate 10 and directly connected to the first electrode layer 111a, and the second bias voltage line 115 can be disposed on a side of the second electrode layer 111b close to the second dielectric substrate 20. Of course, a first insulating layer is further disposed on a side of the layer where the first electrode layer 111a and the third electrode layer 211a are located close to the liquid crystal layer, and a second insulating layer is further disposed on a side of the layer where the second electrode layer 111b and the fourth electrode layer 211b are located close to the liquid crystal layer.

[0095] For example, when the first electrode layer 111a includes a first transmission line 1111 and the second electrode layer 111b includes a second transmission line 1112, the first transmission line 1111 is electrically connected to the first bias voltage line 114, and the second transmission line 1112 is electrically connected to the second bias voltage line 115. When the first electrode layer 111a includes a first transmission line 1111 and a second transmission line 1112, and the second electrode layer 111b includes multiple first patch electrodes 2112, both the first transmission line 1111 and the second transmission line 1112 are electrically connected to the first bias voltage line 114, and the multiple first patch electrodes 2112 are electrically connected to the second bias voltage line 115. When the third electrode layer 211a includes a third transmission line and the fourth electrode layer 211b includes a fourth transmission line, the third transmission line is electrically connected to the third bias voltage line 214, and the fourth transmission line is electrically connected to the fourth bias voltage line 215. When the third electrode layer 211a includes a third transmission line and a fourth transmission line, and the fourth electrode layer 211b includes multiple second patch electrodes 2112 , the third transmission line and the fourth transmission line are both electrically connected to the second bias voltage line 115 , and the multiple second patch electrodes 2112 are electrically connected to the second bias voltage line 115 .

[0117] An embodiment of the present disclosure provides an electronic device, which includes the above-mentioned antenna array.

[0118] The antenna array provided in the embodiment of the present disclosure also includes a transceiver unit, a radio frequency transceiver, a signal amplifier, a power amplifier, and a filtering unit. The antenna in the antenna array can be used as a transmitting antenna or as a receiving antenna. Among them, the transceiver unit may include a baseband and a receiving end. The baseband provides a signal of at least one frequency band, such as a 2G signal, a 3G signal, a 4G signal, a 5G signal, etc., and sends a signal of at least one frequency band to the radio frequency transceiver. After the antenna in the communication system receives the signal, it can be processed by the filtering unit, the power amplifier, the signal amplifier, and the radio frequency transceiver and then transmitted to the receiving end in the transceiver unit. The receiving end may be, for example, a smart gateway.

[0119] Furthermore, a radio frequency transceiver is connected to the transceiver unit and is used to modulate the signals sent by the transceiver unit or to demodulate the signals received by the antenna and transmit them back to the transceiver unit. Specifically, the radio frequency transceiver may include a transmitting circuit, a receiving circuit, a modulation circuit, and a demodulation circuit. After the transmitting circuit receives various types of signals provided by the baseband, the modulation circuit can modulate these various types of signals provided by the baseband and then transmit them to the antenna. The antenna receives the signal and transmits it to the receiving circuit of the radio frequency transceiver. The receiving circuit transmits the signal to the demodulation circuit, which demodulates the signal and transmits it to the receiving end.

[0120] Furthermore, the RF transceiver is connected to a signal amplifier and a power amplifier, which are then connected to a filtering unit, which is connected to at least one antenna. When the communication system transmits signals, the signal amplifier is used to increase the signal-to-noise ratio of the signal output by the RF transceiver before transmitting it to the filtering unit. The power amplifier is used to amplify the power of the signal output by the RF transceiver before transmitting it to the filtering unit. The filtering unit may specifically include a duplexer and a filtering circuit. The filtering unit combines the signals output by the signal amplifier and the power amplifier, filters out noise, and then transmits them to the antenna, which radiates the signal. When the communication system receives signals, the antenna receives the signal and transmits it to the filtering unit. The filtering unit filters out noise from the signal received by the antenna and transmits it to the signal amplifier and power amplifier. The signal amplifier amplifies the signal received by the antenna to increase the signal-to-noise ratio. The power amplifier amplifies the power of the signal received by the antenna. The signal received by the antenna is processed by the power amplifier and the signal amplifier before being transmitted to the RF transceiver, which then transmits it to the transceiver unit.

[0121] In some examples, the signal amplifier may include various types of signal amplifiers, such as a low noise amplifier, which is not limited herein.

[0122] In some examples, the antenna array provided by the embodiments of the present disclosure further includes a power management unit, which is connected to a power amplifier to provide the power amplifier with a voltage for amplifying the signal.

Those skilled in the art will appreciate that various modifications and improvements can be made without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
