Abstract
An antenna apparatus includes a plurality of antennas having different resonance frequencies and a feeding section for supplying common power to feeding terminals of the plurality of antennas. Open terminals of the plurality of antennas are separate. As at least one of the plurality of antennas is implemented as a helical antenna having a helical conductor section trimmed, the transmission-reception band can be put into a wide band. Further, an antenna apparatus includes a plurality of antennas, a connection conductor provided between the antennas for connecting the antennas in series, a feeding section provided in one of terminal sections to which the connection conductor is not connected in the plurality of antennas connected in series, and an additional conductor provided in the other terminal section to which the connection conductor is not connected, wherein the additional conductor is an open end part.
