ABSTRACT:
The receiving device according to this invention includes one or more patch or helical antennas and one or more receiving units formed monolithically on a single substrate. In order to widen the receiving frequency band, antenna elements are formed not directly on a compound semiconductor substrate but with a space between the antenna element and the substrate. In the patch antenna embodiment, patch elements are supported by dielectric posts, whereby there is provided a void between most of the patch antenna and the underlying semiconductor substrate.
