    Abstract

    For calibration of circular phased arrays, a highly omnidirectional horizontally polarized UHF antenna was required. Commercially available antennas are not omnidirectional enough for this application. In this project we compared several potential designs including an electrically small loop, curved crossed dipoles and n-petal wheel. 5-petal wheels had the best simulated performance so we then optimized it and built a prototype. The prototype was measured to be omnidirectional within +/- 0.4 dB. Detailed suggestions were made for further improving the design.
