1. An antenna comprising:
an array of radio-frequency (RF) radiating antenna elements and operable to generate two beams simultaneously in response to interacting with two propagating waves at a same time, wherein the array is part of a metasurface; and
a feed structure coupled to feed the two waves to the array of RF radiating antenna elements, the feed structure having a first waveguide beneath the RF radiating antenna elements in which the two waves propagate in opposite directions.
