Performance Characteristics Of a Reflector Ultra Wideband Impulse Radiating Antenna

Abstract

In this paper, CST-MS was use 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 bandwidth and antenna factor of the antenna were also calculated. The antenna is wideband, non dispersive, directive and has low VSWR. The basic concept of IRA is reviewed. The reflector IRA was designed, analyzed and simulated in CST-MS. The near-field and far-field characteristics of the reflector IRA are studied using the frequency domain results.
