UWB antenna design

Abstract

Reduced ground plane UWB antenna with rectangular patch on FR4 substrate is designed and its analysis is presented in this paper. Performance analysis was carried out for return loss, VSWR, radiation characteristics and impedance matching for the resonance frequency of 6.85 GHz. HFSS tool is used for simulation and the result shows multi resonance characteristics with bandwidth of 6.7 GHz in UWB range with VSWR of 1.4. Proposed structure is optimized to yield the impedance of 47.5 Ω. Better results are obtained on compared with the similar results of the previous work.
