Kind Code:

A1

Abstract:

The horn antenna according to one embodiment of the present invention comprises a waveguide tube part and a horn part. The waveguide tube part has a first dielectric block and a first post wall. The first post wall: includes a plurality of conductive columnar bodies that pass through the first dielectric block; and demarcates a first waveguide that extends in one axial direction. The horn part includes a first widening part that is connected to one end of the waveguide tube part in the one axial direction. The first widening part has a second dielectric block and a second post wall. The second dielectric block is thicker than the first dielectric block. The second post wall: includes a plurality of conductive columnar bodies that pass through the second dielectric block; and demarcates a second waveguide that widens with increasing distance from the first waveguide.
