Abstract

A miniaturized quadruple band reject UWB-MIMO antenna with high degree of isolation is designed and experimentally evaluated in this study. The reported design utilizes dual antenna elements that are organized orthogonally by employing polarization diversity. Notch bands can be acquired by incorporating three U-shape slots and a split ring resonator (SRR) on the antenna element that exhibits band rejection of 3.41-4.07 GHz, 4.41-4.76 GHz, 5.21-5.64 GHz and 6.92-8.63 GHz to reject the potential interference from 5G, INSAT, WLAN and X-band. The UWB-MIMO antenna is resonating in the frequency band from 2.9 to 12 GHz with a good isolation (<-25 dB). The response of the reported antenna has been examined experimentally in terms of notch frequencies, surface current variation, gain, radiation patterns, envelope correlation coefficient, diversity gain, and total active reflection coefficient.
