Abstract

In today's modern communication industry, antennas are the most important components required to create communication link. Multiple Frequency antenna is an antenna which works at multiple frequencies in which one part of antenna is active for one particular band of frequency. An L- shaped single feed multi-band circular polarized slot antenna is simulated in this project. The analysis and design of antenna structure is poised with two non concentric circular slots which are fed by a step impedance feed line. The proposed antenna is designed to operate at multiple bands in multiple frequencies. The output parame ters like return loss, gain, axial ratio, and VSWR are measured for the corresponding frequencies. The simulation of this antenna structure is carried out by using HFSS software
