FIELD: circularly polarized antennas. ^ SUBSTANCE: proposed circularly polarized multifrequency antenna has reflector, first pair of crossed dipoles operating at first resonant frequency, and second pair of crossed dipoles operating at second resonant frequency. First and second pairs of dipoles are symmetrically disposed on one side of reflector and designed for excitation with equal power at relative phase shift through 0, 90, 180, and 270 deg. ^ EFFECT: ability of ensuring multifrequency communications with omnidirectional pattern at desired angle of inclination. ^ 22 cl, 4 dwg |
