Abstract This paper proposes a compact multi-bits chipless RFID tag using fully printed resonators with dual performance of tagging and sensing temperature. Each bit is modelled as curl resonator coupled to microstrip line on metal-backed Rogers RO4003 substrate. The proposed model characterized by high attenuation − 10 dB narrow bandwidth power reflection 3.2 dB. A parametric study the effect ...

This article proposes an alternative method for designing miniature waveguide filters based on locally resonant metamaterials. Implementation of ultra-small metamaterial (metafilters) using the subwavelength direction mechanism in hollow waveguides loaded with small resonators. In particular, composite pin are used, constructed from a metal tube set pins that spaced over deep distances. such st...
