Abstract

A compact Sub-6 GHz Multiple-input Multiple-output (MIMO) antenna based on a complementary split-ring resonator (CSRR) and electromagnetic bandgap (EBG) is proposed in this paper. The antenna has an interesting structure and a compact size of 38×38 mm2. Four identical antenna elements are deposited orthogonally to each other, using polarization diversity and adding decoupling structures, so that good isolation and miniaturized size can be obtained. The isolation is less than -17.5 dB in the operating bandwidth of 3.28-3.62 GHz and -19.5 dB in 4.78-5.04 GHz. The simulation results are consistent with the measured ones, indicating that the antenna is suitable for Sub-6 GHz communication equipments.
