Design of a compact dual-band-rejection microwave filter based on metamaterials transmission lines

摘要

In this paper, a practical study and simulations about the transmission lines and microwave filters metamaterials at the base of the resonance elements is proposed. The Split Ring Resonator (SRR) and the Complementary SRR (CSSR) are coupled with the transmission lines in order to show the electromagnetic properties of metamaterials devices, and their transmission and reflection characteristics for each structure. A novel concept of a compact dual band rejection microwave filter with a high selectivity in the frequency and miniature size is designed. The theory of metamaterials, the NRW approach (Nicolson-Ross-Weir), are briefly introduced.
