Abstract:
1. A slot antenna, comprising: a tubular electromagnetic wave radiation part having a hollow space; a plurality of electromagnetic wave radiating slots for radiating electromagnetic waves being formed in at least a part of a first side surface of the radiation part; a plurality of feeding slots for being inputted with the electromagnetic waves, the plurality of feeding slots being arrayed in line in an array direction orthogonal to a direction of tubular extent of the radiation part in a second side surface arranged opposite to the first side surface; a feeding part having a hollow space, extending along the feeding slot array, and for feeding power from a power input point of the radiation part to the feeding slots; a power guiding part having a hollow space and for guiding the power to the feeding part, the power guiding part extending in a direction orthogonal to the array direction of the feeding slots and in parallel to a center axis of the direction of tubular extent of the radiation part, from a location of the feeding part corresponding to at least one of the feeding slots; and a bulged portion made of an electrically conductive material, formed in at least a portion of an inner wall of the feeding part.
