Antenna unit and antenna system

Abstract

An antenna unit, including a radiator, a dielectric layer and an antenna ground plane which are sequentially stacked. The radiator includes a first antenna unit and a second antenna unit that are opposite to, spaced apart from and structurally complementary to each other. The first antenna unit is provided with a feeding point connected to an external power source and two first grounding points connected to the antenna ground plane. The second antenna unit is provided with three second grounding points connected to the antenna ground plane. Compared with the related art, the antenna unit provided by the present disclosure works in the 37-42.5 GHz band, has a good antenna performance, wide working band, simple structure, and low profile, and is easy to implement.
