Abstract:

To reach the main electrical indicators needs of leaky coaxial cables for a mobile communication system, a Ushaped leaky coaxial cable is designed, satisfying the engineering application. The coupling loss and transmission loss are elaborated. At the operating frequency 900 MHz, the Ushaped leaky coaxial cable modeling is simulated in the 3D electromagnetic simulation software HFSS, and the effect of the variation of interval and slot size on coupling loss and transmission attenuation are analyzed. The simulation results are in good agreement with experimental results. It shows that the smaller the sub slot interval is, the smaller coupling loss is.

Key words: leaky coaxial cable, HFSS;interval, coupling loss.
