Abstract
Abstract The microwave integrated apparatus comprises a housing (4) having a radiation aperture (5). The housing is electromagnetically shielded except for said radiation aperture (5). An insulated substrate (9) is disposed in the housing (4); and an antenna pattern (1) is formed on the insulated substrate. The antenna pattern is capable of receiving or radiating a microwave signal through the radiation aperture (5) of the housing (4). A signal processing means (2) such as a frequency converting circuit is disposed beside the insulated substrate (9) in the housing (4). The signal processing means (2) is connected to the antenna pattern (1) on the insulated substrate (9).
