Design of dual-band MIMO monopole antenna with high isolation using slotted CSRR for WLAN

Abstract

In this article, we proposed a dual-band multi-input multi-output (MIMO) antenna using slotted complementary split ring resonator (CSRR). The designed MIMO antenna for WLAN at 2.45 and 5 GHz provides high isolation with the slotted CSRR inserted on the ground plane. The measured gain and efficiency of the designed MIMO antenna was 4.025 dBi and 86.64%, respectively. The calculated envelope correlation coefficient of the proposed antenna was 0.016, which is suitable for a MIMO system. © 2014 Wiley Periodicals, Inc.
