ABSTRACT:
In an antenna device according to the present invention, a circular ring-shaped dielectric substrate has a radiation electrode formed on its one main surface and a ground electrode formed on its other main surface. In a vacant space portion of the dielectric substrate, a circular convex portion of a first base member is fitted, with an electronic circuit being fixed in the circular convex portion. The radiation electrode and the electronic circuit are connected to each other by a feeder line. Since the electronic circuit connected with the microstrip antenna is accommodated within the vacant space portion of the dielectric substrate, a compact and thin antenna device may be obtained.
