とを特徴とするダイバーシチアンテナ。[Claims for Utility Model Registration] Two rectangular radiating elements arranged side by side at a predetermined interval on one surface of the dielectric substrate and a ground conductor provided on the other surface of the dielectric substrate form two microstripes. In a diversity antenna constructed by forming a microstrip antenna and switching or combining the feed points of the two microstrip antennas as a diversity branch, the excitation directions of the two microstrip antennas are perpendicular to each other. A diversity antenna characterized in that positions of feeding points for feeding power to each radiating element are determined respectively so that
