A compact UWB elliptic antenna for indoor localization system

Abstract

In this letter, a compact low cost ultra-wideband elliptic antenna was presented and discussed. The proposed antenna is printed on a 1.6 mm thick FR4 with size of 21 × 27 × 1.6 mm³. It was composed of a 4 ellipses radiating patch and a reduced ground plane with three rectangular slots. The measurement shows that the considered antenna operates over a wide impedance bandwidth of 16.26 GHz (3.12 GHz to 19.38 GHz) with a maximum Gain of 6 dBi with an omni-directional radiation pattern. Details of simulation and experimental results are presented and discussed.
