Abstract
The invention provides a small portable radio apparatus including a slot antenna member. The slot antenna member has an improved form disposed in a casing. The casing has a curvedly bulging side edge surface. Thus, there is no useless space in the casing reducing the size of the portable radio apparatus. The slot antenna member has first and second conductive plates which form a slot groove at an outer peripheral edge of the first and second conductive plates. A short-circuiting element short-circuits the conductive plates with each other over the slot groove. A tuning capacitor element is connected to the first and second conductive plates at a position opposite to a position where the short-circuiting element is provided. The radio apparatus casing has a side portion which curvedly bulges toward an outer periphery thereof. The first and second conductive plates have central portions with openings and side portions which bulge slantingly toward outer peripheral edges thereof.
