Claim Text:
1. A waveguide connecting structure, comprising: a first waveguide including a pair of electric field planes and a pair of magnetic field planes; a second waveguide including a pair of electric field planes and a pair of magnetic field planes; a third waveguide including a pair of electric field planes and a pair of magnetic field planes; and a fourth waveguide including a pair of electric field planes and a pair of magnetic field planes, wherein the third waveguide has a first coupling window formed at one of the magnetic field planes of the third waveguide, a second coupling window formed at one of the electric field planes of the third waveguide, a third coupling window formed at the other one of the electric field planes of the third waveguide, and a first shorted plane and a second shorted plane that close ends of the third waveguide, the first coupling window couples one end of the first waveguide to the third waveguide in such a manner that the electric field planes of the first waveguide are in parallel with the electric field planes of the third waveguide, the second coupling window couples one end of the second waveguide to the third waveguide in such a manner that the electric field planes of the second waveguide is in parallel with the magnetic field planes of the first waveguide, and the third coupling window couples one end of the fourth waveguide to the third waveguide in such a manner that the electric field planes of the fourth waveguide is in parallel with the magnetic field planes of the first waveguide.
