1. An antenna comprising:
an aperture having
a segmented wedge plate radial waveguide comprising a plurality of wedge plates that form a plurality of sub-apertures, wherein each sub-aperture includes one of the plurality of wedge plates and a distinct subset of radio-frequency (RF) radiating antenna elements in an array of RF radiating antenna elements, wherein each wedge plate of the plurality of wedge plates has a feed point to provide a feed wave for propagation through said each wedge plate for interaction with its distinct subset of RF radiating antenna elements in the array, and
a plurality of RF chains and a plurality of ports, wherein one RF chain in the plurality of RF chains is coupled to one port of the plurality of ports and each port is associated with one sub-aperture of the plurality of sub-apertures.
