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.
