Abstract

This article presents a dual-port circular patch CPW (coplanar waveguide)-fed multiple-input-multiple-output (MIMO) antenna for ISM band (5.8 GHz) applications. The antenna achieves an impedance bandwidth of 1.64 GHz (5.22–6.86 GHz). The optimized dimension of the MIMO antenna is 30 mm × 16 mm. The MIMO structure is obtained by putting the antenna elements orthogonally and fed independently. The matching and isolation of the MIMO antenna are improved by using a rectangular stub associated with the feed and ground plane. The individual antenna has gain and radiation efficiency of 2.52 dBi and 92%, respectively. The antenna has a stable radiation characteristic at 5.8 GHz and co- and cross-polarization are also studied. The performance characteristics of the proposed antenna are dissected as far as the envelope correlation coefficient (ECC), diversity gain (DG), mean effective gain (MEG), total active reflection coefficient (TARC), isolation between the ports, and the values are 0.28, 9.90 dB, ±3 dB, −7 dB, 12 dB, respectively.
