Annular ring slot antenna designs with cp radiation

4.3% for annular and square ring-slot, respectively. In addition, the 2 2 ring-slot antenna array with a 3-dB AR bandwidth of 15% is presented in [4], but the frequency of the minimum AR value is not the same as the fundamental resonant frequency. In this article, we propose a novel design of CP slot antenna to

Abstract: A new design of a microstrip-line-fed circularly polarized printed ring slot antenna is proposed. Circular polarization (CP) radiation of the proposed design is achieved by introducing proper asymmetry in the ring slot structure and feeding the ring slot using a microstrip line at 45/spl deg/ from the introduced asymmetry.
