Abstract
An apparatus for communication of electric or electromagnetic signals over air includes a transmitter or receiver and a coupler. The coupler has a capacitive circuit connected with an air-core or dielectric-core transformer. The capacitive circuit resonates with the transformer at a preselected frequency. The coupler eliminates noise and is matched to the characteristic impedance of the air at the preselected frequency, which linearizes communication and allows high-speed data and voice communication over long distances.
