<p>An antenna apparatus (101) is configured from: a substrate (40); various kinds of electrodes formed on the substrate (40); and a chip antenna (50) and circuit elements (62-66), said chip antenna and circuit elements being mounted on the substrate (40). The resonance frequency of a parasitic radiation electrode (48) is higher than the resonance frequency of 3/4 wavelength resonance of a first feeding radiation electrode, said 3/4 wavelength resonance being generated by means of electrodes (45, 46) and an electrode (53), and multiple resonances are generated with the two resonances. A circuit element (62) is connected in series to a power supply terminal (first end (P11)) of a feeding radiation electrode, and the coupling quantity of the two resonances is correctly specified with a value of the circuit element.</p> |
