Cosite interference between wire antennas using the finite-difference time-domain method

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 the coupling between wire elements; e.g., monopole, and 'towel bar' antennas, mounted on ground planes and helicopter airframes. These results are validated by comparing them with measurements.
