Abstract

The invention provides a patch radiation unit and an array antenna. The patch radiation unit comprises a radiation element, a feed element and a microstrip bonding pad. The feed element and the radiation element are connected in an inserting manner and are welded and fixed through respective bonding pads; and the feed element is arranged right below the radiation element and is mounted on the microstrip bonding pad. According to the patch radiation unit provided by the invention, the characteristics of low profile, enough wide bandwidth and high cross polarization ratio are realized, resonance is formed by adding inductive and capacitive structures to improve the working bandwidth of the radiation unit, the working bandwidth of the radiation unit is expanded to 3300-3800MHz, and the cross polarization ratio is improved by using four-side chamfers.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a patch radiation unit and an array antenna. Background technique [0002] As the requirements for communication in life are getting higher and higher, higher speed and more massive data exchange are required, which leads to the development and change of communication. Today, the 5G era and the trial commercial deployment of 5G networks have ushered in, marking that the integration of base station main equipment and large-scale array antennas will inevitably become a 5G communication trend. The demand for massive MIMO antennas will be much greater than traditional antennas. At the same time, the demand for 5G The portability and low cost requirements of the antenna are getting higher and higher. [0003] However, large-scale antenna arrays in the 5G era have higher requirements for the radiation unit, including increasing the working frequency band for transmitting information,...
