Abstract
A multi-polarized continuous transverse stub (CTS) antenna includes a first feed network operative to at least one of receive or transmit a signal having a first polarization, and a second feed network different from the first feed network and operative to at least one of receive or transmit a signal having a second polarization different from the first polarization. At least one parallel-plate region is defined by a first plate structure and a second plate structure spaced apart from the first plate structure, where a first coupling structure connecting the first feed network to the parallel-plate region and a second coupling structure connecting the second feed network to the parallel-plate region. A common aperture is arranged on one side of the parallel-plate region, wherein wavefronts produced by the first and second coupling structures and propagated within the parallel-plate region radiate to free-space through the common aperture.
