Calculation of Mutual Coupling between Wire Antennas by Applying Variational Principles in FDTD
FDTD结合变分法计算线天线间耦合度

Self impedance,mutual impedance and coupling of antennas are crying out for engineering application, but they can not be easily accurately calculated. The scheme that combines variational principles and the FDTD is presented in this paper to calculate the mutual impedance of wire antennas and the coupling coefficients. Numerical results obtained here have a good agreement with that from FEKO and NEC, which validate the accuracy and efficiency of this method.
