Design and Simulation of Circular Textile Antenna with C- Slot

Abstract

The Circular patch antenna with a C Slot is developed to operate at 4.95 GHz using textile material. These structures are developed using textile materials like Zelt as radiating element and Felt as substrate material. The results of simulations are observed to give better performance with arrays rather than a single antenna in HFSS Software tool. The developed antennas report good performance when compared to existing antennas. The parameters used to compare the two antennas are Gain, VSWR, Return Loss, Efficiency, etc to suit human body. The gain and efficiency for 2 element array were improved by 37.8% and 7.8% respectively over that of single antenna with a tradeoff in bandwidth by 22.7%.
