Abstract
Abstract PURPOSE:To enable fine adjustment of the amount of coupling through the formation of coupling region with ease of manufacture, by opposing two transmission lines parallelly in circular arc shape and constituting the arc rotationably around its center. CONSTITUTION:The two transmission lines 1-1' and 2-2' to be coupled are opposed in parallel on the circular arc 9 taking 8 as the center with a given distance. To obtain the desired coupling performance with this construction, the distance is adjusted and the coupling region 10-11' is in fine adjustment by relatively revolving the both lines 1-1' and 2-2'.
