Abstract
A coupling device for coaxial cable which can maintain coaxial transmission mode of low loss is provided. In the coaxial cable coupling device of the capacitor coupling type, in the case where center conductor coupling electrodes for connecting between center conductors of the coaxial cables and external conductor coupling electrodes for connecting between external conductors are used, electric length of the external conductor coupling electrode is set to length of substantially one fourth (1/4) wavelength, or length of multiple of odd number of substantially one fourth (1/4) wavelength of a passing signal. Thus, transmission by the coaxial transmission mode is carried out at an extremely low loss.
