CIRCULARLY POLARIZED WAVE DOUBLE-HUMPED BEAM ANTENNA
PROBLEM TO BE SOLVED: To provide a thin antenna with small air resistance for a double- humped circularly polarized wave beam. SOLUTION: An angular cross-shaped dipole radiation element 11 formed by crossing two angular-shaped dipoles 12 at right angles is arranged at a height over a reflecting plat...

description | PROBLEM TO BE SOLVED: To provide a thin antenna with small air resistance for a double- humped circularly polarized wave beam. SOLUTION: An angular cross-shaped dipole radiation element 11 formed by crossing two angular-shaped dipoles 12 at right angles is arranged at a height over a reflecting plate 13 of h=0.25λ0 and four vertical parasitic elements 15 with height of h are arranged symmetrically in relation to a cross point F. By adding the parasitic element to the cross dipole radiation element, a good characteristic, with double-humped circularly polarized wave beam direction =55 deg., deviation of azimuthal direction =0.2 dB, and the circularly frequency band with the axial ratio of or less than 3 dB = approximately 6%, is achieved. |
