Abstract

PURPOSE:To increase the coupling electric field at reception point, to make easy the excitation and to avoid the effect by environment, by twisting a pair of more spiral cables having spiral conductors having opposite spiral direction. CONSTITUTION:A pair or more spiral cables 21, 22 having spiral conductors 11, 12 with opposite spiral direction are twisted. For example, the spiral conductors 11, 12 are wound on the external circumference of core members 41, 42 made of insulating material with opposite direction and inner insulation coatings 51, 52 are made on the respective external circumference to form a pair of spiral cables 21, 22. A pair of cables 21, 22 are twisted mutually, and an outer insulation sheathe 3 is made to the external circumference, allowing to form a waveguide of inductive radio communication between mobile bodies such as car and tram car through the insullation of the cables along a road and rail way.
