Abstract :
Measurements of the input impedance of helical antennae in the L-band are presented. The IEEE-bus facility among the various measuring equipment was introduced to facilitate the measurements. The effect of employing a novel feed finger arrangement has been investigated, practical results show that a considerable improvement in the performance can be achieved by including the feed finger in the construction of the antenna.
