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.
Claims17
A polarized wave separator, comprising:
- a substrate portion having an opening portion;
- a pair of wave receiving portions formed on said substrate portion on opposite sides of said opening portion;
- a waveguide located on one side of said substrate portion and having a partition wall portion within;
- and
- a wave reflecting unit located on another side of said substrate portion and having a wave reflecting surface formed inside the wave reflecting unit,
- said waveguide, said substrate portion and said wave receiving unit forming a wave-guiding space,
- said partition wall portion penetrating said opening portion and extending to said wave reflecting unit to divide said wave reflecting surface into two, and
- said partition wall portion partitioning said wave-guiding space into two wave-guiding spaces, one wave-guiding space having one of said pair of wave receiving portions located therein and another wave-guiding space having another one of said pair of wave receiving portions located therein.
