A circularly polarized compact flat source
Abstract
An antenna which can be circularly polarized and molded to the shape of an aircraft, rockets, satellites, etc., is described. The laminated radiating source contains printed circuits and is sized in terms of 0.34 x 0.34 x 0.16 lambda, where lambda is lowest frequency of the band. The antenna is the equivalent of two crossed dipoles fed in phase quadrature. The fabrication of a model operating at 2 GHz with a 40 percent bandwidth is reported. The monolithic nature of the source is suggested to offer the possibility of constructing arrays with several thousand antennas.
