Abstract
A waveguide-microstripline transformer comprises a waveguide which is closed at one end and has a slit at a side wall thereof, a dielectric substrate plate placed on the slit, a microstripline placed on the dielectric substrate plate, and a shield case covering the dielectric substrate plate, whereby less blocking of the incident electromagnetic wave is attained.
