Abstract:

This paper describes main electrical characteristics and their relationships of leaky coaxial cables with periodic slots,and analyzes the influence factors of main electrical characteristics theoretically.The effect of the angle and length of eight-shaped slots on electrical characteristics are investigated,and a leaky coaxial cable with periodic eight-shaped slots is designed by computer full wave simulation method.The measurement results are in agreement with the simulation results,and the design meets the standards of the leaky coaxial cables for railway wireless communication.

Key words: wireless communication;leaky coaxial cable;eight-shaped slot;electrical characteristics
