ABSTRACT:
A plurality of dual feed half square wave antenna element (each of U-shaped onfiguration) are arranged in a log-periodic structure. The antenna elements are feed at the current loops; i.e., at the corners of the U-shaped antenna elements. A dual inphase feed produces vertical polarization signals of low angle radiation, and a dual antiphase feed produces horizontal polarization signals of high angle radiation.
