Abstract
A network is disclosed for matching impedance of an antenna including a first conducting layer to a circuit impedance. The network is adapted to modify at least reactance of the antenna impedance to be substantially equal in magnitude and opposite in sign relative to the circuit impedance. The network includes a first component for modifying the reactance. The first component may form a capacitance in series with the antenna. The network also includes a second component for modifying resistance and the reactance of the antenna impedance. The second component may form a capacitance in parallel with the antenna. The first and second components preferably comprise a second conducting layer adjacent the first layer.
