Abstract
A projecting part is formed on the bottom surface of a dielectric substrate and a first conductive layer and a second conductive layer are respectively formed on the top surface and the bottom surface of the dielectric substrate. A plurality of through holes are formed along the left and the right of the projecting part. A coplanar line including a center electrode sandwiched between two grooves is provided on the top surface. Two slots connected to the top end of the coplanar line are formed at a position corresponding to the position of the projecting part, whereby a waveguide formed by the projecting part and the coplanar line are interconnected via the slots.
