Compact circular-sided microstrip antenna for circular polarization

Development of a new compact circular-sided microstrip antenna is presented. This antenna offers considerable area reduction compared to standard rectangular microstrip antenna designed for the same frequency. Typical antenna design and experimental results for circular polarization are also demonstrated. The antenna has a 3-dB axial ratio bandwidth of 1.5%. © 2002 Wiley Periodicals, Inc.
