Abstract (en)

In an antenna apparatus, a plurality of divisions of antenna elements (21-24) are formed on a radio apparatus cabinet (41) or on a substrate packaged on the surface of the radio apparatus cabinet (1), the divisions are interconnected together by coils (25-27), and a capacitor (28) is connected in parallel with at least one of the coils. The antenna apparatus is compact and tunable to a plurality of frequencies and has a high antenna gain. <IMAGE>
