Abstract

The disclosure provides a full-band antenna system including a metal backing and a main antenna module. The metal backing includes a header, a middle cover and a lower head. The main antenna module includes a circuit board, a feed part on the circuit board, a ground point and a matching circuit. The circuit board includes a substrate and an earth plate. The feed part and the matching circuit are located on the substrate, and the ground point is on the earth plate. The matching circuit is connected with the feed part, including a variable capacitance. By the variable capacitance of the matching circuit, it is beneficial to adjust the performance of antenna of all range of frequency conveniently and optimize the antenna's radiant efficiency up to the utmost extent.
