In this paper is presented the design and fabrication of an Electromagnetic Band Gap (EMBG) resonator in coupled lines configuration, to obtain tunable Magnetostatic Wave (MSW) Band Stop Resonators using a magnetic material, namely YIG (yttrium Iron garnet) biased by means of an external magnetic DC field. In particular, a microwave tunable resonator configuration based on a MSW resonator, working at frequencies up to 16 GHz has been studied. The specific purpose of this work is to analyze the filtering response of coplanar waveguide (CPW) EMBG magnetically tunable resonators in a band stop configuration. Measurements of the S 21 parameter demonstrate an important attenuation with more than 20 dB of the higher order modes. They exhibit a good selectivity obtained by the combination between EMBG resonators and YIG ones in the frequency range 5-18 GHz. Tunable EMBG YIG resonators from …
