Abstract:

A plurality of dual feed half square wave antenna element each of U-shaped configuration 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.
