ABSTRACT:
A printed-circuit antenna enabling two signals to be received simultaneously. Two layers of radiating elements and corresponding power dividers are provided, one set of power dividers being disposed orthogonally with respect to the other, so as to enable reception of two signals with orthogonal senses of polarization. Either dual linear or dual circular polarization may be achieved through suitable selection of radiating elements. Alternatively, a quadrature hybrid may be coupled, either externally or as an integral part of the antenna, to enable dual circular polarization.
