Proximity coupled MIMO antenna for WLAN/WiMAX applications

Abstract

MIMO is the key to the wireless communication to solve the multipath propagation related issues for 4G technologies. A proximity coupled compact MIMO antenna is proposed for WLAN/WiMAX applications. The overall size of the proposed MIMO on the low cost FR-4 dielectric substrate is 39.63 × 82.15 mm2. The measured result shows more than 10 dB of in-band isolation, envelope correlation coefficient of 0.1, and gain of more than 2.75 dBi in the whole band.
