Abstract

The application relates to an antenna unit, an antenna array and an antenna. The antenna unit includes a metal ground layer, a dielectric substrate and an antenna cell unit; the metal ground layer andthe antenna cell unit are respectively disposed on two opposite surfaces of the dielectric substrate; the antenna cell unit has a parallelogram shape, and the antenna cell unit is disposed in a 45-degree polarization manner; the long side and the short side of the antenna cell unit are two adjacent sides; and at least one short side of the antenna cell unit is provided with a radiating element. The antenna can reduce interference and can improve the detection performance of the radar when the vehicle is in use.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna unit, an antenna array and an antenna. Background technique [0002] With the development of communication technology, people have higher and higher requirements for the communication capabilities of communication equipment such as radar. As a tool for transmitting and receiving electromagnetic waves, the performance of the antenna plays a vital role in the communication capability of the communication equipment. [0003] Taking the millimeter-wave vehicle-mounted anti-collision radar as an example, traditional grid antenna arrays or rectangular series-fed array antennas are usually used to transmit and receive signals. However, the traditional grid antenna adopts the method of feeding rectangular patches in series. In a complex environment, such as when two vehicles meet, the simultaneous transmission and reception of signals between two vehicles...
