Abstract

A new, quasi-frequency-independent, H-plane array of log-periodic dipole array (LPDA) antenna has been developed. Because of the reduced H-plane beamwidth, this configuration is shown to be much more appropriate for immunity testing in the presence of a conducting ground plane, especially for horizontal polarization tests. Also, a new feed configuration greatly facilitates high-power operation. A discussion of H-plane LPDA arrays is presented and details of the design are given. Results of quantitative numerical modeling and experimental characterization of a prototype antenna are given
