Abstract
This article demonstrates a compact design of rectangular MIMO antenna that resonates at a frequency of 2.48 GHz for Bluetooth and WLAN applications. The antenna has a compact size of 50 × 40 mm2 and spacing between the two rectangular patches is maintained as 0.05 λ0 which minimizes the effect of isolation (mutual coupling) between the antennas greatly 40 dB and improvement in the return loss of 43 dB at the resonant frequency. To improve the overall performance of diversity, MIMO antenna systems including the antenna parameters like channel capacity, capacity loss, total active reflection coefficient, envelope correlation coefficient, and total radiation efficiency are calculated. Due to the arrangement of minimal spacing between the antennas, resultant improvement in the directivity, impedance, and antenna radiation pattern of rectangular MIMO antenna is obtained. The rectangular MIMO antenna also exhibits an acceptable average peak gain of 6.044 dBi at that particular resonant frequency used in the Bluetooth and WLAN applications.
