Kai Kai Guan, Ge Zhao, Mei Song Tong
Abstract
A novel a monopole dual frequency MIMO antenna is proposed. The antenna adopts different length of double branch structure, the radiator is broken line processing, the surface current length is increased. In order to improve the isolation of the antenna, the defected ground structure is used and the two radiation elements are symmetrically treated at the same time. The overall size of the antenna is 42 mm 39.7 mm, which is compact and easy to process and integrate. The two frequency points of the antenna are 2.4 GHz and 5.2 GHz, which can be used in WLAN communication. The design structure of the antenna and the influence of different parameters on the performance of the antenna are given.
