ン装置。 A primary radiator that receives circularly polarized microwaves, a circular waveguide that communicates with the same-order radiator, and a circular waveguide installed inside the same circular waveguide that converts the circularly polarized wave incident from the primary radiator into a straight line. It consists of a circular-to-linear converter for converting into polarized waves, a converging device for converging the electromagnetic waves converted to linearly polarized waves behind the circular-to-linear converting device, and a means for rotating the converging device. A feed horn device characterized in that the converging device is rotated to two positions making a relative angle of approximately 45 degrees with a linear transducer.
