Abstract: | As telecommunication systems become more complex and more antennas are placed on the same structure (e.g., helicopter airframe) the problem of interference becomes significant for the performance of the systems. The finite-difference time-domain (FDTD) method is used to calculate coupling between wire elements; e.g., monopoles and loops mounted on ground planes and helicopter airframes. Also, rotor modulation effects on coupling are investigated. All the numerical results obtained by FDTD are validated by comparison with measurements |
