Design of Single Band Concentric Square Ring Patch Antenna for MIMO Applications

The proposed multiple-input-multiple-output (MIMO) patch antenna is operating single band at 5.8 GHz frequency. The concentric square ring patch design computational measured results is proposed for dual ports to resonate single resonating frequency. The antenna characteristics performance metrics including a gain, reflection coefficient, and bandwidth enhancement are reported in the results section. The reflection coefficient is observed at −30 dB, and the impedance wideband is 450MHz. The proposed concentric square ring patch antenna to be use at wireless LAN, Wi-Fi, and ISM band applications. The simulated and measured parameters of proposed concentric square ring patch antenna results were agreed.
