Finite-difference time-domain of HF antennas

The FDTD method with higher-order absorbing boundary conditions is used to model and predict the input impedance and the far-field radiation of electrically short antennas. Far-field radiation results are presented and compared with measurement for HF loop (towel bar) and inverted-L antenna elements used at 10 MHz mounted on a helicopter-like body. Wideband input impedance predictions and measurements are also presented. The computed radiation patterns and input impedance compare well with measurements.<
