On the other hand, in the above design, no complex structure is introduced, and compared with the dual polarized radiating element in the prior art, only the adjusting member is introduced, so that the dual polarized radiating element 100 of the present invention has a simpler structure and shorter debugging and processing cycle.
Preferably, the first half-wave vibrator 20 and the second half-wave vibrator 30 are fixed on the front surface 101 of the dielectric substrate by printing, each vibrator arm is similar to an ellipse in shape, and two ends of each vibrator arm are in a needle tip shape, so that the first vibrator arm 201, the second vibrator arm 202, the third vibrator arm 301 and the fourth vibrator arm 302 jointly represent a plum blossom shape.
Preferably, in one embodiment, the first adjusting member 401 is disposed between two adjacent vibrator arms on the front surface 101 of the dielectric substrate. Specifically, the first adjusting members 401 are disposed between the first dipole arm 201 and the third dipole arm 301, between the third dipole arm 301 and the second dipole arm 202, between the second dipole arm 202 and the fourth dipole arm 302, and between the fourth dipole arm 302 and the first dipole arm 201, and each first adjusting member 401 is coupled with the corresponding two adjacent dipole arms, so that energy coupling between two adjacent dipole arms (between the first dipole arm 201 and the third dipole arm 301, between the third dipole arm 301 and the second dipole arm 202, between the second dipole arm 202 and the fourth dipole arm 302, and between the fourth dipole arm 302 and the first dipole arm 201) is effectively reduced, and energy coupling between the first half-wave dipole 20 and the second half-wave dipole 30 is further reduced, so that isolation between two polarizations of the dual-polarized radiating unit 100 is effectively improved.

Referring to fig. 3, in an embodiment of the dual polarized radiation unit 100 of the present invention, two first adjusting members 401 are disposed on the front surface 101 of the dielectric substrate, and the two first adjusting members 401 are symmetrical with respect to the center of the front surface 101 of the dielectric substrate, optionally, one first adjusting member 401 is disposed between the first dipole arm 201 and the third dipole arm 301, and the other first adjusting member 401 is disposed between the second dipole arm 202 and the fourth dipole arm 302.

The number of the first adjusting members 401 may be 1, 2, 3 or 4.

Specifically, the second adjusting member 402 includes a first adjusting piece 4021 and a second adjusting piece 4022, and a connecting arm 4023 for connecting the first adjusting piece 4021 and the second adjusting piece 4022.

Preferably, two second adjusting members 402 are symmetrically disposed on the opposite surface 102 of the dielectric substrate with respect to one diagonal line, so that the coupling between any two adjacent vibrator arms is adjusted and optimized.
Specifically, by adjusting the size and shape of the second adjusting member 402, the energy coupling between the second adjusting member 402 and the first half-wave vibrator 20 and the second half-wave vibrator 30 can be changed, so that the S parameter convergence of the first half-wave vibrator 20 and the second half-wave vibrator 30 is changed, and the standing wave index of the two is improved.

The shapes of the first coupling piece 501 and the second coupling piece 502 may be rectangular, circular or other polygonal shapes, and are not limited in particular.
In another embodiment, the first adjusting member 401 and the second adjusting member 402 are disposed on the opposite surface 102 of the dielectric substrate. Specifically, the projection of each first adjusting piece 401 on the front surface 101 of the dielectric substrate is located in a gap between two corresponding adjacent vibrator arms, so that each first adjusting piece 401 is coupled and connected with the corresponding vibrator arm; the second adjusting member 402 is configured in the same manner as described above, and each adjusting piece is coupled to the corresponding transducer arm.
In another embodiment, the adjusting member includes only the second adjusting member 402, but not the first adjusting member 401, and the second adjusting member 402 is disposed on the opposite side 102 of the medium substrate, and the detailed design is referred to above and will not be repeated.
Further, the first coupling piece 501 and the second coupling piece 502 are also configured in the above manner, and the details can still be seen from the above, and the description is omitted.
Referring to fig. 6, the dual polarized radiation unit 100 of the present invention can flexibly adjust the number of the first adjusting member 401 and the second adjusting member 402 disposed on the dielectric substrate 10 according to different boundary condition characteristics. Fig. 6 shows an application scenario of the dual polarized radiating element 100 of the present invention.
In this embodiment, when the dual-polarized radiating element 100 is a high-frequency radiating element and the dual-polarized radiating element 100 is embedded in the low-frequency radiating element 200, the first adjusting member 401 is disposed between any two oscillator arms on the front surface 101 of the dielectric substrate of the dual-polarized radiating element 100, so as to reduce the influence of each radiating arm of the low-frequency radiating element 200 on the radiating performance of the dual-polarized radiating element 100. The dual polarized radiating element 100 disposed between the two low frequency radiating elements 200 only needs to provide two opposite first adjusting members 401 on the front surface 101 of the dielectric substrate thereof, so as to reduce the influence of the radiating arms on the low frequency radiating elements 200 on the two sides on the radiation performance of the dual polarized radiating element 100.

As described above, the dual polarized radiating element 100 provided with different numbers of adjusting members can be selected according to different boundary conditions to minimize the influence of other radiating elements on the radiation performance of the dual polarized radiating element 100 of the present invention, thereby optimizing the radiation performance of the antenna as a whole, and since the dual polarized radiating element 100 of the present invention has a simple structure, a short debugging process period and low cost, the development period of the antenna of the present invention can be significantly shortened, and the production, maintenance and repair costs of the antenna can be reduced.
The foregoing is only a partial embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
