Abstract
Impedance optimization is difficult in microwave-band waveguide converters. To solve that problem, this waveguide converter is provided with the following: a waveguide provided so as to introduce microwaves to an antenna that performs input and output in a planar microwave circuit; a terminal waveguide that faces the aforementioned waveguide with the antenna interposed therebetween and connects to said waveguide so as to terminate same; and a conductor plate mounted so as to face the antenna. The conductor plate is electrically connected to at least part of the inside wall of the terminal waveguide.
