<p>The object of the present invention is to provide a small broadband antenna. An antenna is provided with inductance elements (L1) and (L2) magnetically coupled to each other. The antenna includes an LC series resonant circuit composed of the inductance element (L1) and capacitance elements (C1a) and (C1b) and an LC series resonant circuit composed of the inductance element (L2) and capacitance elements (C2a) and (C2b). The plurality of LC series resonant circuits are used for radiation of electromagnetic waves. The plurality of LC series resonant circuits are used as the inductances of a matching circuit for matching the impedance (50©) toward a power source with respect to feed terminals (5) and (6) and a radiation impedance of free space (377©).</p> |
