Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a primary radiator converting a circularly polarized wave into a linearly polarized wave, that is made small in size by reducing the total length of its waveguide. SOLUTION: A couple of ridges 13, having a prescribed height and a prescribed width, are projected from the wall face of a waveguide 10 whose one end has a closed face 10b, and the ridges 13 are arranged opposed on a reference lane P which passes through a center axis of the waveguide 10. A dielectric board 11 is placed in the inside of the waveguide 10 and a straight line part 11a with a prescribed width W and a branch 11b projected from its one side are formed to the dielectric board 11. The straight line part 11a of the dielectric board 11 is extended, in parallel with the reference plane P to allow a probe 12 provided to the branch 11b, to cross the reference pane P at an angle of about 45 degrees.  By configuring a 90-degree phase shift section with the ridges 13 and the dielectric board 11, a circularly polarized wave led into the waveguide 10 can be converted into a linearly polarized wave by the ridges 13 and the dielectric board 11. In this way, the probe 12 can receive the radio wave, converted into the linearly polarized wave in the inside of the ridges 13.
