1. An antenna comprising:
an antenna aperture with a plurality of 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 separated in frequency and propagate the feed wave to the plurality of RF radiating antenna elements of the antenna aperture to have the feed wave with the two frequency bands interact with RF radiating antenna elements of the plurality, the two different frequency bands having different propagation paths in the guiding structure to the RF radiating antenna elements.
