INDOOR CHARACTERIZATION OF POWER DELAY PROFILE USING EQUIVALENT ANTENNA REPRESENTATION IN UNIFORM FDTD LATTICES
Keywords:Channel characterization, power delay profile, 3D-FDTD, electrically small antennas, large computational environments
It is shown that proper representation of transmitting and receiving antennas in indoor environments are decisive for accurate prediction of electromagnetic power transfer parameters using the standard 3D-FDTD method. Due to computational restrictions, large dimensions of the environment require large Yee cells. Therefore, it is not possible to precisely describe all the geometrical details of small antennas. A new approach for description of the discone antenna in 3D-FDTD lattice is presented. The calculations are validated by comparing FDTD results with the polyhedral beam-tracing method and experimental data.
