ABSTRACT:
A high frequency signal processing apparatus having signal line patterns formed on the upper surface of a dielectric substrate has a bias line pattern that extends from each of the signal line patterns. The bias line pattern has a first portion formed on the upper surface of the dielectric substrate, a second portion formed on the lower surface of the dielectric substrate, and a conductor extending through the dielectric substrate for providing an electrical connection between the first and second portions of the bias line pattern. A trap pattern is formed on the lower surface of the dielectric substrate and is connected to the second portion of the bias line pattern at a position spaced a predetermined distance away from the corresponding one of the signal line patterns. The predetermined distance is substantially equal to an odd number multiplied by T.multidot..lambda./4 where T and .lambda. are the periodicity and wave-length of the high frequency signal to be processed. A grounded pattern is also formed on the first surface of the dielectric substrate.
