With the technological advancements and increased daily use of cell phones, tablets and other transmitting portable electronic devices (T-PEDs), the Federal Aviation Administration (FAA) has asked the Radio Technical Commission of Aeronautics (RTCA) to provide a means of certification to validate that the use of T-PEDs during a commercial flight shall not cause adverse effects to the aircraft control, navigation, safety and other critical systems onboard . The RTCA committee has developed the document DO-307 to provide aircraft system susceptibility levels and test methods to determine an aircraft's tolerance to the potential electromagnetic signatures that are produced by T-PEDs. Also the RTCA committee developed DO-294 to provide more guidance on allowing the use of T-PEDs on aircraft . With these two documents, airlines can now certify their aircraft fleet for use of T-PEDs during flights while providing customers with more in-flight entertainment (IFE) services like the use of internet and media streaming to their T-PEDs. This thesis presents an analysis of the antenna performance during T-PED testing in order to improve the test efficiency by reducing the number of test locations. The initial investigation demonstrated that a line-replacement unit (LRU) installed in multiple locations throughout an aircraft can be tested once for T-PED compliance instead of requiring testing at every location in the aircraft, thus significantly reducing test time.
