A Printed UWB Diversity Antenna

This paper presents an ultra-wideband diversity antennaprinted on a PCB. The antenna consists of two squares withan equilateral right-angled triangle which are orthogonally and symmetrically printed on a PCB with a slotted groundplane. A parametric study is conducted to examine the effectsof the slots on the impedance matching and isolation. The simulated and measured results show that the proposedantenna is capable of providing good port isolation of |S21| < -20 dB across the operating bandwidth of 3.1 GHz−6 GHz fora 10-dB return loss with pattern diversity.
