Abstract :
A meander line UHF RFID tag antenna with an efficient matching network has been designed. Wideband matching and good radiation properties were achieved in parallel with small antenna size by increasing the structurepsilas electrical length by meander structure and thus lowering its self-resonant frequency. Antenna was modelled with a FEM-simulator and it showed good performance: matching for global RFID UHF frequency and simulated gain was higher than for an ideal half-wavelength dipole. Matching and backscattering properties were verified by measurements and the results were compared against two commercial Gen2 short dipole -type tags. Both, matching and backscattering properties of the designed tag were found to be competent in this respect.
