<p>The receiving device according to this invention comprises a planar antenna (100) and a receiving unit (200) which are formed monolithically on one and the same substrate (1). For the end of widening its receiving frequency band, patch antennas (101 - 104) as the element of the planar antenna (100) are formed not directly on a compound semiconductor substrate (1) but with a spacing from the substrate (1) and are supported by dielectric posts (12), whereby there is provided a void (11) between most part of an area of the patch antennas (101 - 104) and the compound semiconductor substrate (1). <IMAGE></p> |
