ANTENNA APPARATUS AND RADIO COMMUNICATING APPARATUS
First Claim
1. An antenna apparatus capable of multifrequency resonance, comprising:
- a feed element supplied with electricity;
a single or a plurality of non-feed element (s) disposed over a circuit substrate or outside the circuit substrate having a feeding portion disposed for supplying electricity to the feed element; and
a single or a plurality of coupling portion(s) that electromagnetically couples the feed element to the non-feed element(s), the antenna apparatus resonating in a frequency band of the feed element, the antenna apparatus resonating in a frequency band of the non-feed element.

Abstract
The present invention relates to an antenna apparatus capable of multifrequency resonance and realizes downsizing and multifrequency resonance. The present invention relates to an antenna apparatus capable of multifrequency resonance or a radio communicating apparatus (e.g., portable phone) including the antenna apparatus; toward a feed element connected to and supplied with electricity from a feeding unit of a circuit substrate (printed circuit substrate), a non-feed element is disposed with over the circuit substrate or outside the circuit substrate; and the feed side or the open side of the feed element is electromagnetically coupled to the non-feed element to enable resonance in the frequency band of the non-feed element in addition to resonance in the frequency band of the feed element.
