Our filter is based on a 50 Ohms microstrip feed line, three metamaterial resonators and YIG layer. The feed is supplied with a variable magnetic bias in the range of 0- 200KA/m, the central frequency of the filter varies from 10.10 GHz to 12.05GHz (up to 16% tuning) according to the applied magnetic bias, while achieving a maximum rejected bandwidth of 1.2 GHz.enMicrostrip filters; Metamaterial resonators; Tunable filters; YIGArticle
