Abstract

A square-ring microstrip antenna for CP Operation is proposed. Theoretical modal for an antenna is developed using modal cavity model and circuit theory concept. The proposed antenna is also simulated with MoM-based simulator. Theoretical and simulated results show good agreement with earlier reported experimental results. Antenna has a reduced antenna size and centre frequency as compared to the conventional circularly polarized square microstrip antenna with truncated corners at a given operating frequency. Square-ring with truncated corner shows 19% size reduction as compared to conventional CP microstrip antenna.
