Abstract

An L band half wavelength linear resonator has been fabricated on ferrite substrate by conventional photolithographic technique. Design parameters were estimated by using relations of Bahl and Hammerstad. The response of the device has been studied by using HP 8714 ES Vector Network Analyzer and the resonance frequency has been found to be 1.660 GHz which agrees with the design frequency estimated by Kai Chang formulae. When linear resonator placed in magnetic field the resonant peak in general shifts with increase of magnetic field to higher frequencies. Highly anisotropic behaviour is observed with the direction of magnetic field. This can be exploited for fast change of resonance frequency for device applications
