Spectral and time domains analysis of pentagon UWB antenna with WLAN band-notched using electromagnetic band-gap structures

In this paper, an optimization procedure for the design of pentagon Ultra Wide Band (UWB) antenna with wireless local area network (WLAN) Band notched is presented. The proposed antenna has the capability of operating between 3 GHz to 13 GHz. The antenna parameter design has been verified by the High Frequency Structural Simulator (HFSS) and the commercial field solver packages CST Microwave Studio. The proposed UWB antenna has omnidirectional radiation patterns with a gain variation of 1 dBi to 4 dBi and low distortion group delay less than 1ns over the operating frequency range. As results, the simulation demonstrated reasonable agreement with the HFSS and CST results. And good ultra-wideband linear transmission performance has been achieved in time domain.
