Performance characteristics of a reflector Ultra wideband Impulse radiating antenna

Abstract

In this paper, CST-MS was used to model and simulate an Ultra wideband Impulse radiating antenna using high voltage feeding mechanism. Model views are shown and the results of frequency domain simulation up to 7 GHz are plotted for the UWB Impulse Radiating antenna. The feed and the IRA were simulated for various characteristics like frequency domain reflections, VSWR, insertion loss, radiation pattern and gain etc. The half power beamwidth and antenna factor of the antenna were also calculated. The antenna is wideband, non dispersive, directive and has low VSWR. The basic concepts of IRA are reviewed. The reflector IRA was designed, analyzed and simulated in CST-MS. The near-field andfar-field characteristics of the reflector IRA are studied using the frequency domain results.

A comprehensive review of high voltage wideband and ultra-wide band antennas for IEMI applications

“…By varying Z c and f g , the FoM for the respective configuration can be calculated as shown in table 4. EM simulation of the IRA was carried out by Sidhartha [55] in CST-MS and all the basic parameters of antenna like directivity, beamwidth, VSWR etc were calculated. Giri [51] designed and fabricated a full IRA with 3.66 m with the feed placed at 1.21 m from the from the apex of the reflector is shown in.…”
