Abstract
Abstract In a transmission line device for coupling a wave traveling in a particular direction along a main line to a coupled line, higher directivity is obtained by utilizing dielectric media of dissimilar dielectric constants in the main line and the coupled line, or by changing the relative propagation velocity along the main line with respect to the propagation velocity along the coupled line.
