[PDF] Theory and analysis of leaky coaxial cables with .

Frequency band and coupling loss are the two important parameters of leaky coaxial cables with periodic slots. The frequency band can be predicted by analyzing the arrangement of the slots on the outer shield of the cable, but the coupling loss is not so easy to determine by classical methods. In this paper, the finite-difference time-domain (FDTD) method is used to calculate the electric .

Radiating mode vs Coupled mode leaky cables , Physics

May 05, 2017??? I am trying to understand how leaky cables work, and especially those that permit higher frequencies (I think about 2.4GHz), but I am quite new to electromagnetics in general. For clarification, leaky cables are usually coaxial cables that have apertures in their outer conductor from where an amount of radiation "leaks" out, thus they act like .

A few issues that arise concerning leaky coaxial cable is that the radiation pattern can change with each type of deployment and the grade or quality of leaky coaxial utilized. Some types of cables favor. radiating at the "ends" of the cable while others will change the radiation pattern depending upon length of cable used and the bends and .
