An antenna having a wedge plate-based waveguide with feed segmentation and a method for using the same are disclosed. In one embodiment, the antenna comprises an aperture having an array of radio-frequency (RF) radiating antenna elements and a segmented wedge plate radial waveguide comprises a plurality of wedge plates that form a plurality of sub-apertures, wherein each sub-aperture includes one wedge plate and a distinct subset of RF radiating antenna elements in the array, 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.

Multiband guiding structures for antennas and methods for using the same are described. In one embodiment, an antenna comprises: an antenna aperture with radio-frequency (RF) radiating antenna elements; and a center-fed, multi-band wave guiding structure coupled to the antenna aperture to receive a feed wave in two different frequency bands and propagate the feed wave to the RF radiating antenna elements of the antenna aperture.
