Abstract

PURPOSE:To eliminate the upper limit of the frequencies usee, achieve the expansion of the frequency bands used and achieve the increase to the sensitivity in the frequency bands used by suppressing the dhape resonance of antenna elements by changing over with a load matching approximately to the element while not in operation by means of a changing-over means.
