Embodiment Construction
[0031] see Figure 1 to Figure 6 , Embodiments of the present invention include a radiation layer 1 , a horizontally polarized or circularly polarized feed waveguide layer 2 , a vertically polarized feed waveguide layer 3 , and a vertically polarized feed waveguide cover plate 4 .
[0032] The present invention comprises steps:
[0033] ① The radiation layer 1 is designed according to the working frequency, and the radiation layer 1 is used to complete the resonance between the antenna and the space electromagnetic wave. The radiating layer 1 is designed with an array radiating surface of M×N radiating units 11 according to antenna gain requirements, where M or N is a natural number greater than 1. The more radiation units 11 in the array, the higher the gain, the embodiment is that 2×2 radiation units 11 are combined to form an array radiation interface, see figure 2 shown. Each radiation unit 11 is made of aluminum alloy material with precision machining, and its size is...
