Patent attributes
The antenna unit includes a first radiation patch, a feed structure, a second radiation patch, a ground plate, and an insulating dielectric layer. The first radiation patch is electrically connected with the ground plate. The feed structure includes a feeding post and an outer ring. The feeding post passes through the insulating dielectric layer and the ground plate, and one end of the feeding post is connected with the second radiation patch, the other end of the feeding post extends out of the ground plate. The ground plate is provided with a first avoidance hole for avoiding the feeding post, and an outer wall surface of the outer ring is connected with an inner wall surface of the first avoidance hole. The feeding post is coaxial with the feeding outer ring and arranged separately from the feeding outer ring. A dual-frequency and a dual-polarization are formed in the present disclosure.
