Abstract
A first transmission line and a second transmission line are caused to be partially opposite to each other, and by use of the opposite portions of the first transmission line and the second transmission line, the first transmission line and the second transmission line are relatively shifted in parallel from their opposite state to their non-opposite state.
Claims2
A directional coupler including a first non-radiative dielectric transmission line and a second non-radiativc dielectric transmission line which are partially opposite to each other and extending substantially in a first linear direction, opposite portions of the first transmission line and the second transmission line being relatively shiftable in the first direction in parallel and operative to be shifted between an opposite state where electromagnetic coupling occurs and a non-oppositc state where substantially no electromagnetic coupling occurs.
