Abstract [en]

The isolation between antennas needs to be considered when integrating antennas on vehicles, since poor isolation between antennas can cause interference between radio systems on-board. The electrical size of vehicles at gigahertz frequencies often limits the usage of full-wave methods. This paper therefore evaluates two efficient methods to approximate the antenna isolation; the non-singular transmission integral (NSTI) method and the geometric theory of diffraction (GTD). We present the first evaluation of NSTI for antennas outside line-of-sight (non-LOS). It is shown to provide a 6.5 dB RMS accuracy in the early non-LOS zone for an antenna position sweep on an aircraft at 2 GHz, and for frequency sweeps on a cube and cylinder, the latter only to 5 GHz. The GTD implementation gives a 4.4 dB RMS accuracy for cylinders and simplified aircraft models. Both investigated methods give remarkably accurate results, considering memory requirements and runtime, which makes them interesting for further investigations.
