An experimental study of the nearly square circularly polarized microstrip antenna with a rectangular ground plane is presented. Results indicate that circular polarization characteristics of the nearly square microstrip antenna are greatly affected by the different side lengths of the rectangular ground plane. To compensate for this effect, the aspect ratio of the nearly square radiating patch should be increased when the aspect ratio of the ground plane increases. Details of the experimental results are presented. © 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 37: 93–95, 2003; Published online in Wiley InterScience (www.interscience.wiley.com).
