Embodiment Construction
[0014] refer to figure 1. A wideband microstrip antenna array feeding coupling structure includes a microstrip patch antenna array body. The microstrip patch antenna array body is composed of several antenna radiation units provided with coupling slots, the length setting mode of each antenna radiation unit coupling slot is to decrease from the middle to both ends on the array body, and the same length coupling slots are provided. The antenna radiating elements are arranged in pairs on the microstrip patch antenna array body. The microstrip patch antenna array body is composed of several longitudinally arranged antenna radiation units arranged on the dielectric support 9, each antenna radiation unit is provided with a coupling groove 3 below the radiation patch 1, and each radiation patch The coupling slots 3 below 1 are arranged sequentially from left to right, and the length of the coupling slots of each antenna radiating unit is along the length direction of the microstri...
