Abstract
An efficient electrically small circularly polarized SATCOM antenna includes two crossed half loops which are encapsulated by a capacitive cage structure which acts as an internal matching network for the antenna. The cage structure induces two orthogonal electric fields which are 90 degrees out of phase, which produces omni-directional circularly polarized radiation patterns. The gain and impedance performance surpasses that of prior art of similar size.
