B.Moradia, O.Ymbern, J.Alonso, J.Garcia

This paper reports the design of a stop-pass and band-pass filtering EBG structure operating in the Ku band by using thick film high dielectric constant resonators. The design is based on a micro-strip line that periodically loaded with a new kind of dielectric resonator fabricated with a commercial high dielectric constant epoxy paste which compatible with serigraphy and screen printing technology. The geometry of the resonator has been chosen in such a way that, the filtering structure appears below the first resonant frequency. An equivalent circuit model of the proposed structure is discussed and compared with electromagnetic simulations and measurements.
