[0018] The present invention will be further explained below in conjunction with the drawings.
[0019] reference figure 1 As shown, one embodiment of the present invention is a microstrip antenna unit, which includes a first dielectric substrate 2 with a main radiating patch 1 on it and a second dielectric substrate 4 with a parasitic patch 3 on it. The second dielectric substrate 4 is arranged above the first dielectric substrate 2; then a covering dielectric plate 5 is arranged above the second dielectric substrate 4, and a grounding plate 6 is arranged below the first dielectric substrate 2; The reflector 7, the reflector 7 is made of metal material, and its function is to make the energy radiated by the main radiation patch 1 more concentrated; in this embodiment, the H-shaped groove 8 needs to be prefabricated on the aforementioned ground plate 6, and The H-shaped slot 8 is connected to the microstrip line 9 for feeding, and in order to ensure high isolation in the use of d...
