      Currently many airborne platforms (missiles, targets, and projectiles) contain multiple instrumentation systems to cover the functions of GPS and either telemetry, beacon tracking and/or flight termination. Most of these platforms are not very large, so mounting of various antennas to support these functions are physically close to each other. As a result, unwanted interference (in the form of RF coupling between them) is unavoidable. This paper will discuss the design considerations involved to minimize this interference as well as some lessons learned with its implementation.
