Analysis and improvement the isolation between antennas on airborne platform with traveling wave antennas method

Isolation between antennas is an important index for electromagnetic compatibility (EMC) on airborne platform. A solution which is adding traveling wave antennas to ameliorate the isolation between interfered antennas mounted on airborne platform is proposed in this paper. According to the radiation pattern and the absorbed characteristic of terminal impedance of traveling wave antenna, the harmful electromagnetic wave of a certain region could be absorbed and the isolation is improved. The method is validated by calculation and analysis.
