Abstract
A pair of wave receiving probes is provided on opposite sides of an opening portion formed in a substrate. A waveguide is provided on one side of the substrate, and a wave reflecting unit is provided on the other side of the substrate. The wave reflecting unit is provided with a wave reflecting surface on an inner side of its end surface portion. A partition wall in a stepped pattern is provided in the waveguide, which penetrates the opening portion and extends to the end surface portion, thereby dividing the wave reflecting surface into two. The partition wall partitions the wave-guiding space formed by the waveguide, substrate and wave reflecting unit into two spaces. Accordingly, a polarized wave separator excellent in separating characteristics and preventing wave loss is realized.
