摘要：
In this paper, a compact dual-band MIMO antenna for WI-MAX and WLAN applications with improved isolation is proposed. The proposed design consists of two counter facing F shaped monopoles placed closely to each other with edge to edge spacing of 10mm (0.1167λ0 at 3.5GHz). Each monopole element operates over 3.5 and 5.8GHz bands. The isolation over the operating dual bands is achieved by using an elliptical slot and a rectangular parasitic strip. S11 < −10 dB is achieved over 3.2-3.8GHz and 5.7-6.2GHz with S12 < −20 dB. The overall dimension of the proposed antenna is 30 × 26mm2. The proposed antenna has correlation coefficient < 0.03, diversity gain > 9.8dB with stable radiation pattern over the operating dual bands. The measured results are in good agreement with the simulated ones. The proposed antenna is a suitable candidate for MIMO applications. © 2018, Electromagnetics Academy. All rights reserved.
