Abstract
The septum is extended through the opening to the radio wave receiving portion to separate respective polarized waves received by a pair of radio wave receiving portions, and a space between the septum and the radio wave receiving portion is set such that an end surface of the waveguide on the side of the substrate is surely in contact with a grounding surface provided on one surface of the substrate, and an end surface of the radio wave reflecting portion on the side of the substrate is surely in contact with the grounding surface provided on the other surface of the substrate.
