ABSTRACT:
A means for feeding or extracting radio frequency energy from an antenna element which uses coaxial transmission line, without upsetting the antenna elements physical or electrical symmetry, thus providing improved standing wave ratios and near theoretical radiation patterns. Because coaxial cable is inherently unbalanced, double reactance cancellation and resistance transformation are integrally provided by a feed loop shunted across the antenna element improving performance.
