Abstract
In a multi-resonance antenna, at an open end of a radiation electrode of a feeding element and an open end of a radiation electrode of a parasitic element capacitance loading electrodes and ground electrodes are arranged opposite to each other. In the opposing portions, electric-field deflectors are provided, thus reducing the electric-field coupling between the feeding element and the parasitic element.
