Abstract
An antenna includes an antenna element in which feed and non-feed radiation electrodes are formed on a dielectric base; and a substrate having a non-ground area in which a ground electrode is not formed. The antenna element is provided in the non-ground area of the substrate. Each of the feed and non-feed radiation electrodes has a radiation electrode by which fundamental and harmonic waves resonate, a capacitance-loading terminal is formed at a position of the antenna element where an electric field distribution of the harmonic wave becomes a node, and a power supply terminal is formed at a feed end of the feed radiation electrode. A power supply terminal connection electrode connected to the power supply terminal and a capacitance-forming electrode for causing a capacitance to occur between the power supply terminal connection electrode and the capacitance-forming electrode portion are provided on the substrate.
