Anisotropic ferrite microstrip antenna simulation and analysis

This article takes research on the impedance and radiation properties of anisotropic magnetized ferrite microstrip antenna using SO-FDTD method. The author derives the iterative formula of three-dimensional magnetized anisotropic material and confirms it correct in a numerical method. The author also calculates and simulates the ferrite microstrip antenna and plots its return loss, input impedance and radiation pattern. The results show that many different properties are shown in the ferrite microstrip antenna compared with general antenna when the magnetic field is constant. By varying the placement of the antenna, different resonant frequency, under whose effect the radiation characteristics is affected by the magnetic field, can be attained.
