Resonance frequency and external field in multiconductor transmission line

This paper addresses an efficient method to calculate the resonance frequency in multiconductor transmission lines, with a good accuracy. This frequency is the most critical to pick up external fields, experimentally is shown. Crosstalk effects of the multiconductor about a ground plane are analyzed, as well as disturbances due to external electromagnetic fields. As experimental results the behavior of mulitransmission line of finite length of near and far field are presented. An equivalent circuit is proposed for simulation of this phenomenon, and we are obtained that the theoretical-experimental results are in agreement.
