Ground modified double-sided printed compact UWB antenna

A double-sided printed compact antenna for UWB application is proposed. The proposed antenna, having a total size of 30×22 mm, consists of a patch fed by a microstrip line and a partial ground plane. The modified ground plane with triangular shaped slots on its top edge helps to increase the bandwidth of the proposed antenna. The double-sided printed antenna has a bandwidth (VSWR≤2) from 3.08 to 15.90 GHz and a maximum gain of 5.9 dBi. Antenna radiation patterns show stable variation within its operating band.
