1. An antenna assembly comprising;
a backplane;
a polymer substrate mounted over the backplane to define an air gap between a rear surface of the polymer substrate and the backplane, wherein a front surface of the polymer substrate supports a plurality of radiating elements, each of the plurality of radiating elements comprising a polymer-based waveguide feed stalk and a polymer-based pair of radiating arms supported by and electrically coupled to said waveguide feed stalk;
a conductive layer formed on the rear surface of the polymer substrate such that the conductive layer faces the backplane, wherein the conductive layer comprises a first feed line that connects to first polarization radiators of the plurality of radiating elements and a second feed line that connects to second polarization radiators of the plurality of radiating elements; and
a phase shifter positioned in the air gap that is configured to adjust the phase of at least a first sub-component of an RF signal that is passed to a first of the radiating elements.
