Abstract

PURPOSE:To form a small-sized and low-cost null directive antenna regardless of the frequency in order to use it for elimination of the multi-path of the TV, etc., by using directly two units of the on-the-market antennas featuring the same characteristics as well as installing a short-circuit rod.
