PROBLEM TO BE SOLVED: To provide a wireless communication line that can ensure a service area according to a wireless environment by simply varying the leakage and directivity and reduce even a coupling loss between mobile bodies altogether. SOLUTION: In the wireless communication line, a main body 1, where a center conductor 2 is coaxially placed in the center of an extended cylindrical metal-made outer conductor 3 with an opening 4, and an induction coupling section 5, where an outer conductor 7 and a signal induction line 6 to be fitted to the opening 4 are arranged, are provided, and an antenna element 9 is connected to the signal induction line 6. Thus an optimum radiation pattern can be created at a position on a transmission line for desirable radio wave radiation by adjusting respective amplitudes and phases and revising the length L of the antenna element can freely revise the operating frequency band in a live line state.
