Abstract
A compact planner patch ultra-wideband (UWB) antenna is presented in this paper. The antenna configuration consists of a spectacles-shaped patch and a slotted ground plane. Different parameters are investigated for improving the antenna’s properties and for achieving the preferred UWB band (3.1–10.6 GHz). The experimental and simulated results demonstrate that the proposed antenna acquires an operating bandwidth of 117% (3–11.5 GHz) with a stable omnidirectional radiation pattern, about 89% of average radiation efficiency and 4.2 dBi of average gain with the maximum of 5.7 dBi at 10.2 GHz.
