Abstract
In this paper, a compact MIMO antenna with improved isolation is proposed for WLAN applications. The overall dimension of the antenna is only 35 mm × 62 mm. Two identical monopole patch antennas are backed by a modified ground plane. Three rectangular cuts on each antenna element along with modified ground plane are responsible for higher isolation of about 40 dB at 5.5 GHz. The antenna prototype is printed on FR4 substrate (εr=4.4, tanδ=0.02) of thickness 1.5 mm. The measured result show that the −10dB impedance bandwidth of 5.25 − 5.75 GHz for WLAN. The reflection coefficient, mutual coupling, current distribution, radiation patterns, and gain have been simulated to justify the functionality of the MIMO antenna.
