A new TLM modelling method has been developed for patch antennas on magnetized ferrite substrate. The antenna has magnetically controllable resonance frequency and beam direction. The anisotropic permeability tensor of ferrite is modelled by state equations derived from the Polder tensor. Simulation results agree with measurement. © 2001 John Wiley & Sons, Inc.
