Asymmetric Single Split Resonator for RFID Applications

This paper presents a new Asymmetric Single Split Resonator (ASSR) structure for single negative and/or double negative metamaterial applications and its characteristics. The uniplanar structure is a modified split ring resonator with a single split and the prototype is analyzed based on reflection coefficient and unit cell simulations. It exhibits high field confinement as compared to SRR, so best suited for filter and RFID applications. The paper presents the constitutive parameters of ASSR for parallel polarization with supporting simulation and measurement results.
