Abstract

The National Institute of Standards and Technology has completed shielding effectiveness/penetration studies on three different aircraft types for the Federal Aviation Administration. The studies are used to understand the cavity coupling characteristics between antennas placed in various compartments inside the aircraft and antennas placed at various angular positions around an aircraft. This document shows how penetration varies as a function of frequency, antenna type, antenna polarization, and cavity susceptibility for a 737-200 passenger jet. The document discusses initial numerical analysis, antenna gain dependence, and ground bounce effects and how they impact the data. Internal coupling between two antennas placed in the aircraft at different locations was studied and a statistical analysis of the insertion loss between various compartments is also presented.
