TLM modelling of microstrip patch antenna on ferrite substrate

INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING, Issue 3 2001
M. I. Sobhy
Abstract 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.

Magnetically tunable microstrip linear resonator on polycrystalline ferrite substrate

MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 11 2007

Abstract A low cost conventional half-wave microstrip linear resonator has been designed at 2 GHz central frequency and fabricated photolithographically by depositing metallic films on prepared LiMnTi polycrystalline ferrite substrate. Resonator characteristics have been examined by keeping it in the low biasing magnetic field values (from 0 to 298 Guass) applied in transverse direction of wave propagation and normal to ground plane. Tunability of 339 MHz (17%) was achieved which is the best reported so far for such a structure for low magnetic field values with a minimum insertion loss of 10.68 dB. © 2007 Wiley Periodicals, Inc.
