A transmission line model of cable to antenna coupling inside a screened room

A coupled-transmission-line model that evaluates the coupling of emissions from a cable to an antenna when both are located within a screened room is presented. The cable is positioned over a conducting bench in the room. The model developed is valid over the frequency range 10 kHz to 30 MHz. Its parameters can be found quickly and can be easily adjusted to account for changes in height, length, location across the bench, and radius of the cable. A method for evaluating the coupling parameters of the model is given. It involves the use of conformal transformations and image techniques.<
