Abstract
A slot array antenna includes: first and second conductive members; and a ridge-shaped waveguide member on the second conductive member and conductive rods surrounding it. The waveguide member has a waveguide face which is opposed to a conductive surface of the first conductive member and which extends along a first direction. The first conductive member includes first and second slot groups each arranged along the first direction. The second conductive member has a throughhole which splits the waveguide member into first and second ridges. Some slots in the first and second slot groups are connected to a waveguide within the throughhole via a waveguide extending between the waveguide face of the first ridge and the conductive surface, and the remaining slots are connected to the waveguide within the throughhole via a waveguide extending between the waveguide face of the second ridge and the conductive surface.
