1. An electronically scanned array antenna comprising:
a plurality of radiating elements, each radiating element comprising a normal mode radiating element and an end fire mode radiating element; and
a feed layer configured to apply signals to each normal mode radiating element and end-fire mode radiating element,
wherein each of the plurality of radiating elements produces a gain between 0 and 5 dBi when a scan angle is at a zenith and when the scan angle is at a horizon.
