The development of RFID technology are requiring high performance and low cost tag antennas than ever before. To meet these demands, linear tapering technique is firstly proposed in the design of planar tag antennas. With this strategy, the current distribution along antenna arms is effectively assigned by varying the antenna line width. Compared with conventional ones, the tapered antennas can reduce...
Paper substrate is one of the paramount nominees for radio frequency identification (RFID) tags, for the reason that it is one of the widely and the cheapest available substrates. In this paper, for the first time quadrate bowtie antennas with round corners [1] are realized and analyzed on paper substrate for UHF RFID tags. These inkjet printed antennas exhibit high performance which give freedom...
This paper focuses on the process dependence of an inkjet printed folded dipole antenna based on practical parameters in a typical inkjet printing process. We present the effect of width variations and number of overprinting times on the antenna properties such as gain, radiation efficiency and input impedance. Furthermore we investigate the read range degradation of the tag on which the antenna is...
