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.

Abstract: A three-dimensionally latticed flexible-structure composite, including a three-dimensional lattice formed of longitudinal, lateral and vertical strings and a matrix formed by selectively impregnating the component strings of the aforementioned lattice with a molten plastic, the precursor of the matrix, and allowing the molten plastic adhering to the strings to solidify.
