Abstract (en)

A passive element 33 for transducing a circularly-polarized wave into a linearly-polarized wave is disposed in a conical horn 11, and a short-circuit plate 2 is disposed by being spaced out by a prescribed distance from the passive element 33. The short-circuit plate 2 is disposed on the attachment wall surface 55 between the conical horn 11 and a rectangular waveguide 12, and it has the formation of a slit. The slit extracts only a linearly-polarized wave component, which is propagated to the rectangular waveguide 12. A probe 53 is inserted in the rectangular waveguide 12, and the BS signal received by the probe 53 is transduced into an intermediate frequency signal by a frequency transducer arranged on a RF circuit board 54. <IMAGE>
