Circular polarized wave cone beam antenna

摘要: PURPOSE:To obtain an antenna with cone beam excellent in circular polarized wave characteristics and small occupied volume, by locating a vertical horizontal specified distance vertically giving signal of phase difference 90 deg.. CONSTITUTION:A type microstrip consisting spacer 10 made base 9 dielectric substance or the like, radiating plate 11, power feeding line 15 operating waves, has main toward angle elevator determined advance to plane forms symmetrical axis. Further, loop support 12, radiation elements 13, 14 waves almost same that antenna. antennas are located vertically, deg. electrically is given both antennas.
