Design and analysis of compact metamaterial mimo antenna for wlan applications

Abstract

A compact three-port metamaterial multiple-input-multiple-output (MIMO) antenna using complementary split-ring resonator (CSRR) loaded ground have demonstrated in order to reduce the size and enhance the antenna performance. The antenna is designed on FR-4 material and simulated by HFSS software. Furthermore, the simulated results show that the proposed MIMO antenna achieves the total gain higher than 5 dB, the isolation less than -11 dB, the envelope correlation coefficient (ECC) value lower than 0.015, and the bandwidth of 100 MHz through the entire WLAN band from 2.4 GHz to 2.484 GHz, indicating promises for WLAN applications.
