摘要

In this paper, a compact patch antenna array with dual resonant frequencies is presented. The mutual coupling between array elements can be reduced simultaneously at two frequencies by inserting a simple C-shaped resonator between the radiating patches and etching an inverted C-shaped slot defected ground structure (DGS) on the ground plane. The characteristics of the DGS and the resonator are investigated, respectively. The measured results show that the isolation between the antenna ports has been enhanced about 10 dB and 18 dB at the two operation frequencies with the presence of the proposed DGS and resonator structure.
