Abstract
An apparatus and method for receiving wireless signals couples an antenna input of a receiver to a human body and receives a signal conducting from said body. Impedance matching circuitry lessens signal power loss at the antenna input. Parameters of the impedance matching circuitry can be adjusted based on a detected impedance, a detected signal strength, or the frequency of the signal.
