DEFINITION

Classification: 343/863

(under subclass 862) Subject matter wherein the distributed parameter electrical element of the impedance matching network lies along the path of wave propagation through the network and has a physical dimension progressively increasing or decreasing along the path of propagation to result in a corresponding change in electrical parameters of the distributed parameter element.
