An antenna device includes an antenna body, a circuit board, a joint, a transmission line conductor, and a line conductor. The antenna body includes a magnetic body and a conducting wire wound around the magnetic body in a spiral shape. The joint is disposed on the circuit board and coupled to an end of the conducting wire. The transmission line conductor is coupled to the joint. The line conductor is coupled to one of the end of the conducting wire and the transmission line conductor. At least one of a pattern and a length of the line conductor is changeable to adjust an equivalent impedance value of the antenna body.

Antenna device and method for producing antenna device

An antenna device includes: a plated magnetic body; a conductive wire that is wound around the magnetic body; and a substrate that relays the conductive wire and a connector.

Antenna device, communication apparatus, and method of manufacturing antenna device

An antenna unit includes an antenna prepared by winding conducting wire around a magnetic body. The antenna unit also includes a metal housing to accommodate the antenna. The metal housing includes a first cut-out to allow a magnetic field generated by the antenna to pass through the metal housing.

Antenna unit, communications system with antenna unit, and method of producing antenna unit

An amplifier circuit that amplifies a carrier wave that a transmitting and receiving part has received, and includes a superimposition wave generation part that generates a superimposition wave to be superimposed onto the carrier wave; an amplifying part that adds the carrier wave and the superimposition wave to obtain an amplified carrier wave and outputs the amplified carrier wave; and an amplitude detection part that detects, based on a change in an amplitude value of the carrier wave, that the carrier wave is a predetermined carrier wave that carries a predetermined communication signal. The amplifier circuit outputs the amplified carrier wave when having detected the predetermined carrier wave.
