ABSTRACT:
An antenna is formed by attaching a metallic chassis to a dielectric base plate on which are formed an input electrode, a connector electrode and grounding areas. The metallic chassis has a planar part serving as its radiating part and attachment parts formed by bending mutually opposite edge parts of this planar part substantially perpendicularly thereto, and the input electrode, the connector electrode and one of the grounding areas are each connected to either of the attachment parts. An antenna unit is formed by mounting the metallic chassis of such an antenna inside an opening formed in a printed circuit board on which are formed a feed electrode and grounding electrodes formed with an edge portion of each abutting this opening and by connecting the input electrode to the feed electrode, and the grounding electrode to one of the grounding areas.
