Coaxial to waveguide transducer including an L shape waveguide having an obliquely arranged conductor and method of forming the same

A method of forming a coaxial waveguide transducer, the method comprising:

• providing a waveguide having a substantially L shape formed of a first waveguide part and a second waveguide part arranged substantially orthogonal to each other, the waveguide having one end which is on a side of the first waveguide part to which a coaxial line is connected;
• forming a stepwise step bend part in an outer corner part of an L-shaped bent part of the waveguide;
• arranging a first conductor and a second conductor along respective inner side walls of the waveguide in such a way that the first conductor and the second conductor are extended in the direction in which a central conductor of the coaxial line is extended and are positioned on a plane that is the same as a plane where the central conductor is provided;
• and
• arranging a third conductor in such a way that one end is connected to the central conductor and another end is connected to one of the first conductor and the second conductor, and that the third conductor is extended obliquely with respect to the direction in which the central conductor is extended.
