ABSTRACT:
Microwave apparatus fabricated in stripline is shown to be made up of (a) printed circuitry to form a directional coupler on both sides of a sheet of a dielectric material effectively suspended in space between a pair of ground planes, the printed circuitry being connected by shorting posts passing through the dielectric material; and (b) a matching section, formed from a dielectric material having a dielectric constant greater than unity, overlying portions of the printed circuitry.
