Abstract :
This communication reports the results of an experimental investigation of a new log-periodic (LP) antenna. The antenna consists of an LP array of radial waveguides excited by a two-wire transmission line. The antenna exhibits a vertically polarized omnidirectional radiation pattern which is essentially constant over the designed bandwidth.
