A Compact Dual Band MIMO Antenna with Improved Isolation for Wi-MAX and WLAN Applications
Progress In Electromagnetics Research M, Vol. 68, 69-77, 2018
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 10 mm (0.1167λ0 at 3.5 GHz). Each monopole element operates over 3.5 and 5.8 GHz 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 3.2-3.8 GHz and 5.7-6.2 GHz with S12 < -20 dB. The overall dimension of the proposed antenna is 30 × 26 mm2. The proposed antenna has correlation coefficient < 0.03, diversity gain > 9.8 dB 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.
