Abstract

An optimized ink-reducing hollowed-out arm meander dipole antenna structure for printed RFID tags adi m. j. marindra, pornanong pongpaibool, werayuth wallada and siwaruk siwamogsatham This paper presents an optimized ink-reducing meander dipole antenna structure suitable for implementing printed radio frequency identification (RFID) tags. The proposed antenna designs contain empty ink-reducing hollowed-out areas along the antenna's arms such that the resulting antennas require much less conductive ink to produce yet still achieve decent antenna performance compared with the conventional solid-arm dipole antennas. The simulation results demonstrate that when the ratio between the width of the hollowed-out areas and the width of the antenna arms is about 0.6, the resulting RFID tag experiences a slight read range performance degradation of ,10%, while it offers a sizeable ink consumption reduction of almost 50%.

“…The proposed design of the hollow meander antenna would have a ratio of 0.6. The hollow design must not have a significant deterioration effect on antenna performance [19].…”

UV Curable Conductive Ink for the Fabrication of Textile-Based Conductive Circuits and Wearable UHF RFID Tags

“…To further demonstrate the good prospective application of the UV-curing conductive ink in wearable electronic devices, a fully screen-printed antenna for UHF RFID tag was fabricated. The antenna structure is shown in Figure 4b, and it is a short straight dipole antenna 28 with a total length of 0.25λ. The antennas were screen-printed on fabric substrates, and after the screen printing, they were cured under UV for 20 s. Then, the tag-integrated circuit (IC), which is Alien H3 series RFID IC, was attached to bridge the narrow gap of the antenna by anisotropic conductive adhesives.…”

Novel Concentric Hexagonal-Shaped RFID Tag Antenna With T-Shaped Stub Matching

“…A dual-band antenna for high-frequency band and ultra-high frequency band RFID systems based on the Hilbert-curve fractal is described in [12]. A hollowed-out meander dipole antenna for printed RFID tags is developed in [13] to reduce conductive ink. In [14] dual band functionality for Europe (867 MHz) and Japan (956 MHz) UHF RFID is obtained by using impedance perturbation method in a folded dipole antenna.…”
