CIRCULARLY POLARIZED TURNSTILE ANTENNA WITH WIDE BEAM-WIDTH

摘要

PURPOSE: A circularly polarized turnstile antenna with a wide beam-width is provided to maintain stability even in case of cosmic environments by improving a radiation pattern and the beam width of an axial ratio pattern. CONSTITUTION: An antenna unit radiates a radio wave in circular polarization to the space. A feed structure transfers the radio wave to a dipole. A Balun intercepts a leakage current. A reflector(31) guides the radiation of the antenna unit to the front direction. A reflection wall(32) increases the beam width property of the antenna unit.
