[0061] First embodiment

[0062] As shown in Figures 1, 2, and 3, Figures 1, 2, and 3 are respectively a three-dimensional view, a top view, and a bottom view of the phase mode control unit provided in the first embodiment. It can be seen that the phase mode control unit is mounted on two dielectric substrates: a first dielectric substrate 1 and a second dielectric substrate 2. The upper surface of the first dielectric substrate 1 is printed with an n-shaped feed line 3 and a first symmetrical patch 4 connected together. A floor 9 engraved with a linear tapered slot antenna 8 is printed on the lower surface of the first dielectric substrate 1. A second symmetrical patch 7, parallel to the first symmetrical patch 4, is printed on the upper surface of the second dielectric substrate 2. A first port 5 and a second port 6 are provided at each end of the n-shaped feed line 3, respectively, and the excitation mode of the ports is direct-connected excitation. It should be noted that the first symmetrical patch 4 is not a required component of the phase mode control unit. It is used to adjust the bandwidth. If a very wide bandwidth is not required, it can be removed to simplify the structure. The specific selection can be made based on actual design requirements.

[0063] In the first embodiment, when the phase difference between the two ports is When , the feed line forms an equivalent magnetic wall at the center of the slot antenna structure, and only the symmetrical patch antenna structure participates in radiation. Almost no current flows through the slot antenna structure. At this time, the phase mode control unit is in common mode excitation mode. When the phase difference between the two ports is When , the feed line forms an equivalent electric wall at the center of the slot antenna structure, mainly because the slot antenna structure radiates, and the electric field on the symmetrical patch antenna structure is very small, which is called the phase mode control unit in the differential mode excitation mode.

[0064] As shown in FIG4 , FIG4 is a reflection coefficient curve of the phase mode control unit of the first embodiment in the common mode excitation mode and the differential mode excitation mode. The operating frequency band of the common mode excitation mode is 24-28 GHz, and the frequency range of the differential mode excitation mode is 23.2-29.2 GHz.

[0065] As shown in Figures 5 and 6, Figures 5 and 6 are the radiation patterns of the phase mode control unit of the first embodiment in the common mode excitation mode and the differential mode excitation mode in the two directions of Phi = 90° and Phi = 0°, respectively. It can be seen that in the common mode excitation mode, the radiation pattern of the phase mode control unit is a side-fire mode, and in the differential mode excitation mode, the radiation pattern of the phase mode control unit is an end-fire mode.

[0066] As shown in Figure 7, Figure 7 shows the actual gain values ​​of the two radiation modes of the phase mode control unit provided in the first embodiment. In the operating frequency band of 24-28 GHz, the gain of the common mode excitation mode is about 7 dBi, and the gain of the differential mode excitation mode is about 4.5 dBi.

[0067] For the above-mentioned Sagami control unit, this embodiment provides a design method, including the following steps:

[0068] S1. Determine the initial dimensions of the radiator and slot antenna structure in the module control unit.

[0069] As an optional embodiment, the side radiator works in TM 01 Taking the mode as an example, the size of the side-emitting radiator is 0.25λ0-0.75λ0, where λ0 represents the wavelength of the electromagnetic wave in vacuum at the center operating frequency f0.

[0070] S2, by controlling the phase difference between the two ports to be or This enables the phase mode control unit to form an equivalent magnetic wall or an equivalent electric wall, thereby enabling the radiation pattern of the phase mode control unit to be switched between the side-fire mode and the end-fire mode.

[0071] As shown in FIG8 , based on the aforementioned phase model control unit, this embodiment further provides a scanning array. The scanning array in this embodiment includes four phase model control units arranged linearly. It should be noted that the multiple phase model control units can be arranged in a straight line, a curve, or other arrangement shapes. This application does not limit the arrangement shape of the multiple phase model control units.

[0072] In the scanning array of the first embodiment, the phase module control unit is fine-tuned to serve as an array element of the phased array.

[0073] As shown in Figure 9, which is a graph of active reflection coefficients for two radiation modes of the scanning array provided in the first embodiment, the four phase mode control units in the array can operate in a bandwidth of 24-28 GHz in both common mode and differential mode excitation modes.

[0074] Figure 10 shows the test and simulation results of the 26 GHz scanning pattern of the scanning array of the first embodiment operating in broadside radiation mode, as shown by the solid and dashed lines in Figure 9. With a 3 dB gain drop and a -5 dB sidelobe level, the scanning array can achieve beam scanning within a range of -55° to +55°.

[0075] Figure 11 shows the test and simulation results of the scanning pattern at 26 GHz for the scanning array of the first embodiment operating in end-fire radiation mode, as shown by the solid and dashed lines in Figure 9. With a 1.5 dB gain drop and a -5 dB sidelobe level, the scanning array can achieve beam scanning within a range of -65° to +65°.

[0076] As shown in Figure 12, which is a gain curve of the scanning array provided by the first embodiment at 24-28 GHz, the gain of the common mode excitation mode is about 11 dBi, and the gain of the differential mode excitation mode is about 8 dBi.

[0077] As shown in Figure 13, which is a graph of the total radiation efficiency of the scanning array provided by the first embodiment at 24-28 GHz, the total efficiency of the common-mode excitation mode is approximately 90%, and the total efficiency of the differential-mode excitation mode is approximately 85%.

[0078] Second embodiment

[0079] As shown in Figures 14, 15, and 16, Figures 14, 15, and 16 are respectively the three-dimensional, top, and bottom views of the phase model control unit of the second embodiment. The second embodiment also places the phase model control unit on a two-layer dielectric substrate. The difference from the second embodiment lies in the following: a single-shaped feed line 10 and elliptically symmetrical patches 11 are printed on the top surface of the bottom dielectric substrate; a floor with a fixed-width slot antenna 15 is printed on the bottom surface of the bottom dielectric substrate; and a diamond-shaped symmetrical patch 14 is engraved on the top surface of the top dielectric substrate. Furthermore, a first coupling port 12 and a second coupling port 13 are provided at each end of the single-shaped feed line 10, indicating that the port excitation method in this embodiment is coupled excitation.

[0080] In the second embodiment, the feeder is shaped like a single-edge antenna, the edge-emitting radiator is a circular patch antenna or a diamond-shaped patch antenna, and the slot antenna is a rectangular antenna with a fixed width. It is worth noting that the various structures described in this invention are not limited in shape; any structure using the design method described in this invention should be protected.

[0081] Third embodiment

[0082] As shown in Figures 17 and 18, which are three-dimensional and top-down views, respectively, of the phase model control unit of the third embodiment, the third embodiment has the same slot antenna structure as the first embodiment, but the shape of the feeder is different, and the radiator with the broadside pattern is also different. While the first embodiment uses an n-shaped feeder 3 and a second symmetrical patch 7, the third embodiment uses an L-shaped feeder 16 and a patch antenna 17.

[0083] Since the feed line in the first embodiment is symmetrical along the y-axis, or When the feeder line is in the center, an equivalent magnetic wall or an equivalent electric wall is formed. However, the feeder line in the third embodiment is not symmetrical along the coordinate axis, so the phase difference between the two ports is or 180°, the center of the feeder does not form an equivalent magnetic wall or equivalent electric wall. and The calculation formula is as follows:

[0084] Where f0 is the operating frequency of the phase model control unit, l p1 is the distance from the left port to the center of the slot antenna structure, l p2 is the distance from the right port to the center of the slot antenna structure, and c is the speed of light in a vacuum.

[0085] It is worth noting that the present invention mentions and The values ​​are not limited, and any parameter value that allows the feed line to form an equivalent magnetic wall or equivalent electric wall at the center of the slot antenna structure should be protected. The radiators with broadside patterns mentioned in this invention are not limited to paired structures. As long as the radiator has a broadside pattern and a TM mode, and the slot antenna structure is located vertically at the center of the broadside radiator, it should be protected within the scope of protection of this application.

[0086] Fourth embodiment

[0087] Figure 19 is a three-dimensional view of the fourth embodiment's Sagami control unit. It can be seen that the Sagami control unit in this embodiment is not mounted on a two-layer dielectric substrate. Instead, it consists of a three-layer metal structure. The first layer is a symmetrical patch antenna structure, secured at the top by two first support columns 18. The second layer is an n-shaped feeder, secured in the middle by two second support columns 19. Both ends of the feeder are excited by coupled feed probes 20 extending through the large floor. The third layer is a large floor 21 with a slotted structure, located at the bottom of the structure.

[0088] In the fourth embodiment, the operating frequency band is microwave, the metal patch is not printed on the dielectric substrate, and the feeder line in the intermediate layer is not connected to any other radiator. It is worth noting that the phase mode control unit and its scanning array described in this invention are not limited to the operating frequency band, the presence or absence of a dielectric substrate, the feeder excitation method, or the shape of the feeder line. As long as the radiator uses the design method described in this invention, it should be protected.

[0089] Fifth embodiment

[0090] This embodiment uses a micro-convex antenna or a dielectric resonator antenna to implement a radiator with a broadside pattern. The other structures are the same as those in the first embodiment. The broadside radiators mentioned in this application are not limited to patch antennas. Micro-convex antennas or dielectric resonator antennas can also be used. As long as the radiator has a broadside pattern and a TM mode, it should be protected within the scope of protection of this application.

[0091] In summary, the present invention discloses a phase mode control unit, a scanning array, a communication device and a method with switchable broadside and end-fire patterns. The phase mode control unit includes a slot antenna structure and a radiator with a broadside pattern. Two ports are used for excitation. When the phase mode control unit operates in common mode, the phase difference between the two ports is The radiation pattern of the unit is in side-beam mode. When the phase mode control unit works in differential mode, the phase difference between the two ports is The radiation pattern of the unit is in end-fire mode, and the radiation pattern of the phase mode control unit can be switched between broadside mode and end-fire mode by controlling the phase difference between the two ports. Broadside mode works in TM mode, and end-fire mode works in slot mode. The phase mode control units are arranged at preset intervals to form a phased array arranged in a planar array or a curved array. Compared with existing solutions, the present invention can achieve switching and scanning of the beam in the broadside direction or the end-fire direction only by controlling the phase difference between the ports. At the same time, no active circuit is required, thereby ensuring high radiation efficiency, simple structure, and low manufacturing cost, which is conducive to the integration and miniaturization of the phased array.
