Abstract
Abstract A microwave integrated apparatus, particularly useful for a satellite broadcasting receiver, comprises a housing having a radiation aperture and being electromagnetically shielded except for the radiation aperture. An insulated substrate is disposed in the housing, and has formed thereon an antenna pattern capable of receiving or radiating microwaves through the radiation aperture of the housing. A signal-processing means is disposed beside the insulated substrate in the housing, and is connected to the antenna pattern on the insulated substrate. For achieving a microwave circuit arrangement having excellent performance characteristic of a very wide frequency range, a second antenna pattern is disposed at the radiation aperture of the housing, and in proximity to the above-mentioned antenna pattern.
