Abstract
An electronic device includes a first transmission line, a second transmission line and a ground-coupling portion. The first transmission line is composed of a first signal line transmitting a given high frequency wave signal and a first ground. The second transmission line is composed of a second signal line transmitting the high frequency wave signal and a second ground. The ground-coupling portion couples the first ground and the second ground. A phase difference between the high frequency wave signals at both ends of the ground-coupling portion is substantially integral multiple of 180 degrees.
