Abstract
An antenna switching arrangement with a quadrature arrangement of transmission lines through which a desired signal path may be configured via switches selectively grounding junctions of the switching arrangement. The desired path routing a signal from an input port to one or both of first and second output ports to generate a signal with vertical linear polarization, horizontal linear polarization or circular polarization. The selected polarization may be changed as desired and/or multiple antenna switching arrangements applied to enable simultaneous signals with different polarizations.
