Transmission line pair
First Claim
1. A transmission line pair comprising:
- a first transmission line; and
a second transmission line which is so placed in adjacency to the first transmission line that a coupled line region is formed, the coupled line region having a coupled line length being 0.5 time or more as long as an effective wavelength in the first transmission line at a frequency of a transmitted signal, wherein in the coupled line region, the first transmission line comprises a first signal conductor which is placed on one surface which is either a top face of a substrate formed from a dielectric or semiconductor or an inner-layer surface parallel to the top face and which has a linear shape along a transmission direction thereof, and the second transmission line comprises a second signal conductor which is placed on the one surface of the substrate and which partly includes a transmission-direction reversal region for transmitting a signal along a direction having an angle of more than 90 degrees with respect to the transmission direction within the plane of the placement, and which has a line length different from that of the first signal conductor.

Abstract
In a transmission line pair including a first transmission line and a second transmission line which is so placed in adjacency that a coupled line region to be coupled with the first transmission line is formed, in the coupled line region, the first transmission line includes a first signal conductor which is placed on one surface which is either a top face of a substrate formed from a dielectric or semiconductor or an inner-layer surface parallel to the top face and which has a linear shape along its transmission direction, and the second transmission line includes a second signal conductor which is placed on the one surface of the substrate and which partly includes a transmission-direction reversal region for transmitting a signal along a direction having an angle of more than 90 degrees with respect to the transmission direction within the plane of the placement, and which has a line length different from that of the first signal conductor.
