Abstract
A circularly polarized multifrequency antenna is described. The antenna includes a reflector having a first side and a second side, a first crossed dipole pair having a first resonant frequency and a second crossed dipole pair having a second resonant frequency. The first and second dipole pair are symmetrically disposed on the first side of the reflector and configured to be fed with equal power in a relative phase rotation of 0°, 90°, 180° and 270°.
