ABSTRACT:
A circuit component for use with signals of superhigh frequency, on the order of 10 GHz or more, has a waveguide structure with four conductive walls defining a channel of rectangular cross-section, the channel bottom being overlain by a dielectric layer supporting at least one microstrip of copper or the like closely spaced from one of the lateral walls. The supporting layer preferably consists of a polymeric material of relatively low dielectric constant, e.g. between 2 and 3. The width and height of the channel are less than half the free-space wavelength of the highest-frequency signal to be transmitted; the circuit is tuned by metallic screws which are threaded into the adjoining wall and partly overlie the microstrip at a low level, the axes of adjacent screws being separated by less than an eighth of that wavelength.
