Abstract
A multi-polarized scanning phased array antenna includes a plurality of elements, a first feed line operatively coupling the plurality of elements, a second feed line operatively coupling the plurality of elements, and a phase delay operatively coupled in at least one of the first feed line and the second feed line. The phase delay is configured to cancel a polarized signal associated with the multi-polarized scanning phased array antenna. A method of increasing isolation between polarizations in a multi-polarized scanning phased array antenna includes coupling a plurality of elements operatively with a first feed line, coupling the plurality of elements operatively with a second feed line, and coupling a phase delay operatively in at least one of the first feed line and the second feed line such that a polarized signal associated with the multi-polarized scanning phased array antenna is cancelled.
