1. An antenna comprising:
a tiled antenna aperture with a plurality of separate non-circular antenna apertures having a plurality of radio-frequency (RF) radiating antenna elements;
a plurality of wave propagating structures;
a plurality of input feeds to feed RF feed waves into the plurality of wave propagating structures; and
a plurality of non-radially symmetric directional couplers, each of the plurality of non-radially symmetric directional couplers being within one of the plurality of wave propagating structures and for coupling power of one RF feed wave of the RF feed waves to one of the plurality of non-circular antenna apertures at a central location within said each sub-aperture antenna aperture to enable the feed wave to propagate outward from the central location to an edge of the aperture.
