Abstract
A waveguide converter includes a waveguide including a hollow section through which a signal is transmitted and a first opening formed on a cross section of the hollow section in a direction orthogonal to a transmission direction of the signal, and a circuit board including on a same surface a signal line, a conductor patch connected to the signal line, and a second opening surrounding the conductor patch. The waveguide is fixed onto the circuit board. The first opening surrounds the second opening. The conductor patch includes a rectangular section which has short sides in parallel with short sides of the first opening, and has a first long side and a second long side connected to the signal line in parallel with long sides of the first opening, and protruding portions which are provided so as to touch the short sides near both ends of the second long side, respectively.
