ABSTRACT:
A compact satellite broadcasting receiver comprises a circular waveguide, a strip-line-shaped probe projected into the circular waveguide, a reflecting element provided downstream of the probe in the circular waveguide and a microwave circuit having a strip line provided around the circular waveguide and connected with the probe. Furthermore, a satellite broadcasting receiver capable of simultaneously receiving two kind of microwaves polarized perpendicularly to each other is realized by joining two compact satellite broadcasting receivers as mentioned above with their strip-line-shaped probes placed at a right angle.
