Experimental Verification of LG WAVE and Ansoft HFSS Simulation Software Using a 2 x 2 Antenna Array with EBG Structure

Abstract

In this paper we are presenting the validation of the LG RF Simulation tool (WAVE) and HFSS simulation software’s through measurement results of the fabricated design, simulated in WAVE and HFSS simulation software’s. A 2 x 2 antenna array with Electromagnetic Band Gap (EBG) structure in the ground plane is simulated using WAVE and HFSS ver. 17.The prototype antenna was fabricated and characterization is carried out at CHRIST (Deemed to be University) Bangalore to know the performance of the antenna array. Return Loss and VSWR of the fabricated antenna are measured using Anritsu S820E Microwave Site Master Network Analyzer. Two - dimensional radiation patterns were plotted and compared with the simulated results obtained from WAVE and HFSS Software’s. From the results of HFSS simulation software we observed that EBG integrated array is exhibitinggainof7.089dB and Return loss of -16.2 dBat2.4GHz.Whereas the results obtained from WAVE simulation tool for the same design gave a peak gain of 5.03 dB and return loss of -12.8dB at 2.4 GHz. Measured gain of the designed array is 7.407 dB and return loss is -7.565 dB at 2.4 GHz.
