Electromagnetic Characteristics Simulation of Leaky Coaxial Cable

Abstract

Based on the technical characteristics of leaky coaxial cables, the application scenarios of regional monitoring system and closed-area mobile communication system for leaky coaxial cables are first analyzed. Then the structure diagram of leaky coaxial cables is introduced, the radiation mechanism of leaky coaxial cables and the analysis method of electromagnetic characteristics are introduced, and the simulation model of leaky coaxial cables is established by electromagnetic simulation software HFSS. The direction pattern and the loss feature of leaky coaxial cables is simulated and analyzed. The simulation results show that the signal of leaky coaxial cable has the characteristics of uniform coverage and low electromagnetic attenuation.
