摘要

This article demonstrates a portable ultrawideband (UWB) diversity antenna with capability of rejecting WLAN band. A circular split ring resonator (SRR) slot is etched out in the patch for filtering out the interference due to WLAN band centered at 5.2 GHz. A partial common ground plane with T-shaped stub is employed for high isolation. A fair correlation is reported between the simulated and experimentally measured findings with |S₁₁| < −10 dB in the operational band. The measured isolation of |S₂₁| < −20 dB along with satisfactory diversity performance metrics prove the utility of suggested antenna for UWB MIMO applications.
