FIG. 11 omits the transmitting circuit 110 and the receiving circuit 120 in FIG. 1, and only shows the dual-polarized antenna ANB and the feeding elements F111 and F112. The feeding elements F111 and F112 may be disposed corresponding to the feeding regions FZ111 and FZ112, respectively. Different from the rectangular antennas shown in FIGS. 1 to 10 and 13, the dual-polarized antenna ANB may be elliptical or circular as described above. The feeding element F111 may include a strip conductor F111A and a transmission line F111B, and the strip conductor F111A may extend parallel to the edge of the dual polarized antenna ANB. In other words, when the dual polarized antenna AN11 is elliptical or circular, the strip Conductor F111A may be arc-shaped (ARC). Similarly, the feeding element F112 may include a strip conductor F112A and a transmission line F112B, and the shape thereof is also the same. Strip conductor F111A and dual polarization There may be a distance DT1 between the edges of the antenna ANB. The distance DT1 may be related to the impedance corresponding to the transmitted signal. For example, if the dual-polarized antenna ANB is applied to the example in FIG. 6 , the transmission line F111B can be disposed at the middle position of the strip conductor F111A to receive the first transmit signal ST1 . Similarly, the transmission line F112B feeding into the element F112 can be used to output the first received signal SR1. Similar to FIG. 1, the dual-polarized antenna ANB may include feeding regions FZ111 and FZ112. The dual-polarized antenna ANB may have an antenna shape center CT, the feeder region FZ111 has a region shape center, and the feeder region FZ112 has a region shape center, and the connection between the region shape center of the feeder region FZ111 and the antenna shape center CT forms a first reference The line DR1, the connection line between the area shape center of the feeding region FZ112 and the antenna shape center CT forms a second reference line DR2, and the first reference line DR1 is substantially orthogonal to the second reference line DR2. The angle AA1 between the feeder area FZ111 and the center CT of the antenna shape is approximately 22.5 degrees to 120 degrees, while the angle AA2 between the feeder area FZ112 and the center CT of the antenna shape is approximately 22.5 degrees to 120 degrees. greater than 180 degrees.

The dual-polarized antenna ANB may have a first antenna surface and a second antenna surface, and a thickness may be formed between the first antenna surface and the second antenna surface. One of the first antenna surface and the second antenna surface may be located on the reference plane, and the position where the strip conductors F111A and F112A are projected on the reference plane may be located outside the dual-polarized antenna ANB, not overlapping. The strip conductor F111A and the transmission line F111B may be parallel to the reference plane (COPLANAR), and the strip conductor F111A may be parallel to the edge of the dual-polarized antenna ANB and have a distance DT1. Similarly, the strip conductor F112A and the transmission line F112B are the same, and can be parallel to the edge of the dual-polarized antenna ANB and have a distance DT2. For example, the dual polarized antenna ANB can be fabricated on a metal layer of a circuit board, such as, but not limited to, a printed circuit board, and the feed element can be fabricated on the same metal layer of the circuit board to form the antenna of FIG. 11 . In another embodiment, the antenna body and the feeding element can be fabricated from different metal layers, and the antenna shown in FIG. 11 can also be formed.

FIG. 12 is a partial schematic diagram of the wireless signal transceiver device in the embodiment. Same as picture 11 Similarly, only the dual-polarized antenna ANB is shown, with the feeding elements F111 and F112. However, in Fig. 12, the position where the strip conductors F111A and F112A are projected on the reference plane can be located inside the dual-polarized antenna ANB, which is different from the dual-polarized antenna ANB. The antennas ANB are overlapped in the vertical direction. The strip conductors of any one of the feeding elements F111 and F112 can be disposed on the same plane (COPLANAR) as the transmission line. The strip conductors can be parallel to the reference plane and have a vertical distance. For example, the dual polarized antenna ANB can be fabricated on a metal layer of a circuit board (eg, but not limited to, a printed circuit board), the feed element can be fabricated on another metal layer of the circuit board, and between the two metal layers This vertical distance can be provided to form the antenna of FIG. 12 . The relationship between the feeding regions FZ111 and FZ112 of the dual-polarized antenna ANB and the antenna shape center CT is similar to the embodiment in FIG. 11 , and the description is not repeated.

In Figs. 11 and 12, the antenna has two feeding elements as an example, but according to an embodiment, an elliptical bipolar antenna can also be provided with four feeding regions as shown in Fig. 8. A feed-in element, similar in application, will not be described repeatedly.

FIG. 13 is a schematic diagram of a wireless signal transceiver 1300 in another embodiment. The wireless signal transceiving device 1300 may be an embodiment of the wireless signal transceiving device 100 . As shown in FIG. 13 , the main difference between the wireless signal transceiving device 1300 and the wireless signal transceiving device 100 is that it further includes a dual-polarized antenna AN2 . The dual-polarized antenna AN2 and the dual-polarized antenna AN1 can be coupled to the transmitting circuit 110 and the receiving circuit 120 together, and can be used to receive the first transmission signal ST1 and the second wireless signal SRX substantially simultaneously (not shown). The dual-polarized antenna AN1 and the dual-polarized antenna AN2 can form a 1×2 antenna array. In other embodiments, one or more dual-polarized antennas commonly coupled to the transmitting circuit 110 and the receiving circuit 120 may also be included to form an M×N antenna array with the dual-polarized antennas AN2 and AN1 . The M×N antenna array can be used to receive a signal (eg, the first transmit signal ST1 ) from the transmit circuit (eg, 110 ), and output the signal (eg, the first receive signal SR1 ) to the receive circuit (eg, 120 ). Parameters M and N may be positive integers greater than zero. For example, in an MxN antenna array, one of M and N may be 1 and the other may be an integer greater than 1. because Here, the M×N antenna array may be a 1×N antenna array, or an M×1 antenna array. In another example, M and N may be positive integers greater than 1.

FIG. 14 is a partial schematic diagram of the wireless signal transceiver device in the embodiment. Similar to FIG. 11 , the transmitting circuit 110 and the receiving circuit 120 mentioned in FIG. 1 or other embodiments are omitted here, and only the dual-polarized antenna ANB and the feeding elements F111 and F112 are shown.

θ<90°。舉例來說，若第一參考線DR1及第二參考線DR2形成兩角度，85度及95度，則銳角θ為85度。 Similar to FIG. 11 , in FIG. 14 , the feeding elements F111 and F112 may be disposed corresponding to the feeding regions FZ111 and FZ112 . In FIG. 14, the connection line between the area shape center of the feeding area FZ111 and the antenna shape center CT may form the first reference line DR1, and the connection line between the area shape center of the feeding area FZ112 and the antenna shape center CT may form the second reference line. Reference line DR2. The acute angle θ formed by the first reference line DR1 and the second reference line DR2 may not be less than 45 degrees; in other words, 45 degrees

θ<90°. For example, if the first reference line DR1 and the second reference line DR2 form two angles, 85 degrees and 95 degrees, the acute angle θ is 85 degrees.

The dual polarized antenna ANB of Fig. 14 may have a circular or elliptical shape.

For example, the feeding elements F111 and F112 in FIG. 14 can be arranged beside the dual-polarized antenna ANB as shown in FIG. 11, wherein the projection area of the dual-polarization antenna ANB may not overlap with the projection areas of the feeding elements F111 and F112 .

For another example, the feeding elements F111 and F112 in FIG. 14 can be disposed above or below the dual-polarized antenna ANB as shown in FIG. 11 , wherein the projection area of the dual-polarized antenna ANB can overlap the feeding elements F111 and F112 projection area.

The feeding elements F111 and F112 can be insulated from the dual polarized antenna ANB. Due to the coupling effect, signals can be sent and received between the dual-polarized antenna ANB and the feeding elements F111 and F112. FIG. 15 is a graph of the acute angle θ versus signal isolation in FIG. 14 . The signal isolation described here is the isolation of the wireless signals transmitted and received by the dual-polarized antenna ANB.

θ)，隔離度可大於8分貝(dB)且落於可接受範圍。當銳角θ從45度增至90度，隔離度可增至約24分貝，又上升到約32分貝，故更可保障訊號品質。 As shown in Figure 15, when the acute angle θ is greater than or equal to 45 degrees (that is, 45°

θ), the isolation can be greater than 8 decibels (dB) and fall within the acceptable range. When the acute angle θ increases from 45 degrees to 90 degrees, the isolation can be increased to about 24 decibels, and then to about 32 decibels, so the signal quality can be guaranteed.

θ<90°，以得到更佳的隔離度。 As shown in Fig. 15, when the acute angle θ is increased to 75 degrees, the isolation degree can be significantly increased as the slope of the graph increases. Therefore, according to an embodiment, the acute angle θ may be not less than 75 degrees. In other words, the acute angle θ can be set to 75°

θ<90° for better isolation.

By using the dual-polarized antenna wireless signal transceiver device provided by the embodiment, only a dual-polarized antenna with a single radiator can be used to substantially simultaneously perform signal reception and signal transmission, thereby realizing object detection or long-distance transmission of signals. application. In addition, between the dual-polarized antenna and the amplifying circuit, the external coupling element or duplexer can be omitted, which is beneficial for reducing the area of the dual-polarized antenna and simplifying the structure and volume of the overall system.

FIG. 16 is a schematic diagram of the wireless signal transceiver device 100 in the embodiment. The wireless signal transceiver 100 may include a dual-polarized antenna AN, a transmitting circuit 110, a receiving circuit 120, and a processing circuit PU. The dual polarized antenna AN can be used to transmit the wireless signal STX and to receive the wireless signal SRX substantially simultaneously. The wireless signal STX can be reflected by the object OBJ to generate the wireless signal SRX.

The dual-polarized antenna AN includes feeding regions FZ1 and FZ2. The feeding region FZ1 is used for receiving the transmission signal ST1, and the wireless signal STX can be generated according to at least the transmission signal ST1. The feeding area FZ2 is used for outputting the received signal SR1, and the received signal SR1 can be generated according to the wireless signal SRX.

The dual-polarized antenna AN can be used to form radiated electric fields E1 and E2. The radiated electric field E1 can have a first co-polarization direction according to the wireless signal STX, and the radiated electric field E2 can have a second co-polarized direction according to the wireless signal SRX. The co-polarization direction and the second co-polarization direction may form a non-orthogonal angle θ1. In the far-field, the non-orthogonal angle θ1 may be between 45 degrees and 135 degrees.

The transmitting circuit 110 can generate the transmitting signal ST1 according to the input signal SI, and the receiving circuit 120 can generate the processing signal SA according to the receiving signal SRI. The processing unit PU is coupled to the transmitting circuit 220 and the receiving circuit 120 for generating spatial information of the object OBJ according to the processing signal SA and the input signal SI.

In FIG. 16, the wireless signal transceiver device 100 can be a radar device. During a period of time, the wireless signal STX can continue to transmit, and at this time, the wireless signal SRX can continue to receive. When the object OBJ moves, a frequency shift can be generated according to the Doppler effect. Therefore, the processing unit PU can determine whether the object OBJ is moving according to the frequency difference between the wireless signals STX and SRX. When the frequency difference between the wireless signals STX and SRX is substantially zero, it can be determined that the object OBJ is fixed.

In other words, the non-orthogonal angle θ2 formed by the reference lines DR1 and DR2 is not less than 45 degrees (45°

θ2<90°), so that the first co-polarization direction and the second co-polarization direction form a non-orthogonal acute angle θ1 on the far-field (far-field), and 45°

FIG. 26 is a top view of the dual polarized antenna AN in the embodiment. As shown in FIG. 26 , the slots SL1 , SL2 , SL3 , and SL4 may be formed in the patch PA and arranged symmetrically around the shape center CT of the patch PA. The positions of the slots SL2 and SL4 may be opposed to each other, and the positions of the slots SL1 and SL3 may be opposed to each other.

θ<90°)或非正交角度θ可介於90度至135度(90°<θ

135°)。換言之，第一參考線DR1及第二參考線DR2形成的銳角θ不小於45度(45°

θ<90°)，以同時達到類似第14圖實施例的功效。在其他實施例中，亦可將第1圖~第13圖、以及第16圖中具有規則形狀的雙極化天線、以及第17圖~第45圖中雙極線天線的具有規則形狀的貼片，藉由加上附加部分APA及/或移除掉一部分以產生開槽/開口SL，從而可改變雙極化天線或雙極線天線的貼片的形狀中心的位置，以使第一參考線DR1及第二參考線DR2形成的銳角θ不小於45度(45°

For example, due to the design of the printed circuit board of the wireless signal transceiver 100 , the trace length corresponding to the transmitting circuit 110 may be different from the trace length corresponding to the receiving circuit 120 . Thus, as shown in Fig. 46, the shape of the patch PA can be adjusted by adding an additional portion APA (eg, a smaller rectangle) to the original portion (eg, a larger regular shape, such as a rectangle), and/or A part is removed from the original part to create a slot/opening SL (eg a smaller trapezoid), so that the position of the shape center CT of the patch PA can be changed so that the first reference line DR1 and the second reference line DR2 are non-orthogonal to each other, and the non-orthogonal angle θ is not equal to 90 degrees. The efficacy of this embodiment will be further explained in FIG. 50 . Regular shapes are, for example, circles, ellipses, rectangles, regular polygons (eg, regular triangles, regular quadrilaterals, etc.). For example, the non-orthogonal angle θ may be between 45 degrees and 90 degrees (45°

θ<90°) or non-orthogonal angle θ can be between 90° and 135° (90°<θ

135°). In other words, the acute angle θ formed by the first reference line DR1 and the second reference line DR2 is not less than 45 degrees (45°

θ<90°), in order to achieve the same effect as the embodiment in Fig. 14. In other embodiments, the regular-shaped bipolar antennas shown in FIGS. 1 to 13 and 16 and the regular-shaped stickers of the dipole antennas shown in FIGS. 17 to 45 can also be used. The patch, by adding an additional portion APA and/or removing a portion to create a slot/opening SL, can change the position of the shape center of the patch for a dual polarized antenna or a dipole antenna so that the first reference The acute angle θ formed by the line DR1 and the second reference line DR2 is not less than 45 degrees (45°

Figure 46 removes a smaller part from the original larger regular shape to create a slot/opening embodiment, which can further produce other effects, please refer to the dual polarized antenna AN as shown in Figure 47 Schematic diagram with circuit element 310 . In a compact device, the area occupied by circuit elements may interfere with the area occupied by regularly shaped patches or antennas. Therefore, as shown in FIG. 47, the shape of the dipole antenna AN, or the shape of the patch PA of the dipole antenna AN, may be a non-convex shape, such as a concave shape. For example, as shown in FIG. 47, the patch PA can be a concave hexagon, wherein the concave hexagon can be created by removing a portion (eg, a larger regular shape) from an original portion (eg, a larger regular shape such as a rectangle). small rectangle) to generate. FIG. 47 is for example only, and does not limit the scope of the embodiments. Similarly, a portion of a circular patch, a portion of a triangular patch, or a rectangular A portion of the shaped patch can be removed, and the resulting space can accommodate the circuit 310.

θ<90°或90°<θ

135°。 In Fig. 47, the shape center FZC1 of the feeding zone FZ1 and the shape center CT of the dual-polarization antenna AN can be connected to form a reference line DR1, and the shape center FZC2 of the feeding zone FZ2 and the shape center CT of the dual-polarization antenna AN can be connected to each other. connected to form a reference line DR2. Because the shape of the patch PA has an irregular shape (such as a complete rectangle, triangle or circle), the position of the shape center CT is not located at the shape center of the regular shape, and the reference lines DR1 and DR2 are not perpendicular to each other. For example, the angle θ between the reference lines DR1 and DR2 may not be equal to 90 degrees, for example, 45 degrees

θ<90° or 90°<θ

135°.

θ<90°)。由於天線形狀中心CT已非位於規則形狀之形狀中心CT0，故可改變參考線DR1與DR2形成的角度θ。 FIG. 48 is a schematic diagram of a dual-polarized antenna AN having a first part PA1 , a second part PA2 and a third part PA3 in an embodiment. The first part PA may have a larger regular shape (eg, a rectangle), and the second part PA2 and the third part PA3 are connected to the first part PA1, so that the antenna shape center CT is not located at the shape center CT0 of the regular shape. The regional shape centers FZC1 and FZC2 of the feeding regions FZ1 and FZ2 can respectively form reference lines DR10 and DR20 with the regular shape shape center CT0 , and the reference lines DR10 and DR20 are substantially perpendicular to each other. The regional shape centers FZC1 and FZC2 of the feeding regions FZ1 and FZ2 can respectively form reference lines DR1 and DR2 with the antenna shape center CT, and the non-orthogonal angle θ formed by the reference lines DR1 and DR2 can be between 45 degrees and 90 degrees, that is, The acute angle θ is not less than 45 degrees (45 degrees

θ<90°). Since the antenna shape center CT is not located at the shape center CT0 of the regular shape, the angle θ formed by the reference lines DR1 and DR2 can be changed.

As mentioned above, by adjusting the positions of the regional shape centers FZC1 and FZC2 of the feeding regions FZ1 and FZ2, the acute angle formed by the reference lines DR1 and DR2 is not less than 45 degrees (for example, as shown in Figure 14); The polarized antenna AN has a notch, so that the acute angle formed by the reference lines DR1 and DR2 is not less than 45 degrees (as shown in FIG. 46 and FIG. 47 ); and/or the dual-polarized antenna AN can have at least a first part and a second part The first part has a regular shape, and the second part is connected to the first part, so that the acute angle formed by the reference lines DR1 and DR2 is not less than 45 degrees (as shown in FIG. 47 and FIG. 48 ).

As mentioned above, the shape center of the two feed areas of the dipole antenna and the shape center of the dipole antenna can form two reference lines, and the two reference lines can form an angle; When the angles formed by the two reference lines are different, the corresponding S-parameters (S-parameters) waveform diagram.

FIG. 49 is a waveform diagram of return loss and isolation when the angle formed by the two reference lines is substantially 90 degrees according to the embodiment. Taking Fig. 6 as an example, the dual-polarized antenna AN in Fig. 6 has a regular shape (such as a rectangle), and the angle formed by the two reference lines is substantially 90 degrees; in this case, as shown in Fig. 49, the curve a1 is a waveform corresponding to the return loss of transmit/receive (Tx/Rx), and the curve a2 is a waveform corresponding to the isolation between transmit and receive. As shown in Figure 49, the best return loss corresponds to frequency fa1, the best isolation corresponds to frequency fa2, and there is an offset between frequencies fa1 and fa2 (eg, 75 megahertz).

FIG. 50 is a waveform diagram of return loss and isolation when the acute angle formed by the two reference lines is substantially between 45 degrees and 90 degrees in the embodiment. For example, in Fig. 14, Fig. 46, Fig. 47 and Fig. 48, the two reference lines are not perpendicular, but can form an acute angle substantially between 45 degrees and 90 degrees. In this case, as shown in FIG. 50, the curve b1 is the waveform corresponding to the return loss of transmit/receive (Tx/Rx), and the curve b2 is the waveform corresponding to the isolation between transmit and receive. As shown in FIG. 50, the best return loss corresponds to the frequency fb, and the best isolation may also correspond to a frequency close to the frequency fb. Therefore, the frequency corresponding to the best return loss and isolation may have little or no offset. Therefore, according to the embodiment, by adjusting the antenna shape center CT of the dual-polarized antenna AN, the included angle between the two reference lines can be between 45 degrees and 90 degrees, and the performance of the antenna can be improved accordingly.

To sum up, the embodiments provide various solutions for designing conductive paths, patches, etc. of the dual-polarized antenna AN so as to transmit signals to the receiving circuit 120 and receive signals from the transmitting circuit 110 . The size and performance of the dual-polarized antenna AN can be more easily adjusted and help improve design flexibility. Especially in some embodiments of the present invention, by adjusting the positions of the regional shape centers FZC1 and FZC2 of the feeding regions FZ1 and FZ2 so that the acute angle formed by the reference lines DR1 and DR2 is not less than 45 degrees, the optimal The frequency corresponding to the return loss and the frequency corresponding to the best isolation degree are too large to cause the problem of poor performance of the antenna, and there is still sufficient isolation between the signals sent and received in the feeding areas FZ1 and FZ2 Spend.
