Data coupler
First Claim
1. A data coupler for coupling data between an electric power line and a communication device, the data coupler comprising:
- a metal wire;
an antenna substrate that is not electrically connected in a DC arrangement to the electric power line;
whereinthe antenna substrate is arranged adjacent to the metal wire;
the metal wire is wound around the electric power line such that ends of the metal wire are not connected to one another; and
the antenna substrate includes a resonant circuit including an inductor pattern and a capacitor pattern.

Abstract
A data coupler includes an antenna substrate that is not electrically connected in a DC arrangement to an electric power line, is arranged adjacent to the electric power line, and is connected to a modem. A resonant circuit including an inductance element and a capacitance element is provided in the antenna substrate. In the resonant circuit, the inductance element is magnetically coupled to the electric power line. The resonant circuit transmits a radio-frequency signal superimposed on the electric power line to the modem. The resonant circuit also transmits a transmission signal from the modem to the electric power line.
