Analysis of the airborne transmission lines and antennas coupling interference

In this paper, we present a theory for the problem of electromagnetic field coupling to a transmission line. Through the numerical calculation, some important coupling characters of external field and transmission lines are elicited. As airborne antennas are strong radiation sources, this paper figures out some methods to control electromagnetic interference of transmission lines according to antennaspsila installation place and their characters. The research results of the project will have practical applications to the transmission line interference in the airplane.
