Abstract
A horn antenna array includes at least two horn antenna elements arranged along a first direction. Each of the at least two horn antenna elements includes a base having a slot extending along a second direction which intersects the first direction, and a horn communicating with the slot, the horn having a pair of electrically-conductive first inner walls intersecting the first direction and a pair of electrically-conductive second inner walls intersecting the second direction. The pair of second inner walls include a pair of opposing protrusions. When radiating an electromagnetic wave, the pair of protrusions create two radiation sources on the inside of the pair of first inner walls.
