An X‐band, end‐coupled ring resonator has been fabricated photolithographically by depositing Cr–Cu–Au film on an LiZnTi polycrystalline ferrite substrate. Resonator characteristics have been studied by keeping it in the magnetic field, which was varied from 0 to 3.0 kG. Broadband tunability of 3.1 GHz was achieved with a minimum insertion loss of −11.17 dB when the direction of the magnetic field was changed from transverse to longitudinal to the wave propagation in coupling lines. © 2001 John Wiley & Sons, Inc.
