ASYMMETRICAL SUPPORTING BODY FOR HIGH FREQUENCY TRANSMISSION LINE

PROBLEM TO BE SOLVED: To provide a high frequency transmission line having stronger mechanical strength of a central conductor than a conventional one. SOLUTION: This support structure for coaxial transmission line is provided with an outer conductor (10) which has a circular external cross section and an asymmetrical internal hole, and wherein a part of the internal hole is coaxial with the external cross section and the rest part of the internal hole is notched by a flat part forming a ground plane (14), a dielectric material (12) supporting a central conductor (11) at the height fixed from the ground plane to be coaxial with the external cross section of the outer conductor, and an electromagnetic absorptive material (13) disposed between parallel parts of the internal hole and the dielectric.
