Design of dual band microstrip antenna based on electromagnetic band gap structure

Abstract

Because the antenna is an important passive component in the RF front-end of mobile communication, some studies have found that the combination of EBG and antenna can effectively improve the performance of the antenna. In this paper, a dual band microstrip antenna based on EBG structure is designed, which improves the gain of the antenna, and the resonant frequencies are 2.4 GHz and 3.5 GHz. After simulation, the return loss at two resonant frequencies is less than −19.5 dB, which basically meets the design requirements.
