When it is less than half-wavelength, the commonly used method is to increase isolators (including various forms such as columnar, sheet-like, and triangular). Because its effectiveness still follows the frequency-variable characteristic, there are still problems of strong coupling, low gain and large size, and it is difficult to meet these requirements at the same time. Therefore, it is of great significance to develop a miniaturized heterogeneous array antenna. Summary of the Invention

[0022] Such as Figure 1 and Figure 2As shown in the figure, a miniaturized heterogeneous array antenna includes a multi-layer gradient director module 1 and a heterogeneous array module 2. Among them, the heterogeneous array module 2 is the core part, which is composed of a tower-shaped isomer base 21, a main element 22, and multiple weighted elements 23. The main element 22 is located at the top of the tower-shaped isomer and plays a main radiation role. The main element 22 is selected as a microstrip antenna to achieve wide-band coverage; while multiple weighted elements 23 are respectively arranged in different directions on the side of the tower-shaped isomer base 21. Through the setting of the isolation sheet 24, the mutual interference between the elements is reduced to ensure independent operation. The side of the tower-shaped isomer base 21 is inclined to optimize the propagation path of electromagnetic waves. The multi-layer gradient director module 1 is arranged above the main element 22, and its gradient structure guides the propagation direction of electromagnetic waves to further enhance the directivity and gain of the antenna.

[0023] Furthermore, in this embodiment, the weighted element 23 is preferably set to six to provide more balanced radiation coverage and higher system redundancy. At the same time, the side of the tower-shaped isomer base 21 adopts an inclined design, which helps to optimize the propagation path of electromagnetic waves, reduce reflection and diffraction, and improve the radiation efficiency of the antenna.

[0024] In terms of frequency band coverage, the operating frequencies of multiple weighted elements 23 can be set to one or more of GNSS, Beidou B3, and B1L1G1E1 to meet the requirements of different communication systems. The operating frequency of the main element 22 includes all the operating frequencies of the weighted elements 23, and can also include the integration of other GNSS frequencies to achieve wide-band coverage and enhance the versatility and flexibility of the antenna.

[0025] In addition, the types of the main element 22 and multiple weighted elements 23 can be flexibly selected, including but not limited to microstrip antennas, helical antennas, dipole antennas, etc., to adapt to different application scenarios and performance requirements.

[0026] This embodiment realizes pattern isolation by constructing a heterogeneous array module. At the same time, through the multi-layer gradient director module, a super strong director shaping technology is introduced. By comprehensively applying the pattern and director technology, it is possible to ensure that the array antenna has a sufficiently small planar size while efficiently utilizing the height space, focusing on improving the passive gain of the central main channel antenna and ensuring the positioning ability of the antenna; realizing the miniaturization, multi-band coverage, and high-efficiency radiation characteristics of the antenna.
