“…One of the main challenges in designing a passive RFID is the impedance matching between the terminals of the tag antenna and those of the IC, which exhibits complex input impedance that is commonly extremely high or low. This requires a conjugate matching technique such as series or parallel stubs and/or using inductive coupling [24]. The matching network of the tag has to guarantee the maximum power delivered to the IC that is used to store the data transmitted to and receive from the RFID reader.…”

Abstract-In this paper, inkjet-printed UHF and microwave circuits fabricated on paper substrates are investigated for the first time as an approach that aims for a system-level solution for fast and ultra-low-cost mass production. First, the RF characteristics of the paper substrate are studied by using the microstrip ring resonator in order to characterize the relative permittivity ( ) and loss tangent (tan ) of the substrate at the UHF band for the first time reported. A UHF RFID tag module is then developed with the inkjet-printing technology, proving this approach could function as an enabling technology for much simpler and faster fabrication on/in paper. Simulation and well-agreed measurement results, which show very good agreement, verify a good performance of the tag module. In addition, the possibility of multilayer RF structures on a paper substrate is explored, and a multilayer patch resonator bandpass filter demonstrates the feasibility of ultra-low-cost 3-D paper-on-paper RF/wireless structures.

“…A general dipole input impedance relation is obtained using the induced EMF method taking the wire radius effect into account, and the relation is verified through comparison with previous published results. Compactness is achieved through designing conventional dipole antenna, meander dipole antenna MDA with derivation of its resonance frequency and Franklin shape dipole antenna which occupies a total area of 1306.6 mm 2 compared with Ushaped slot tag antenna with geometry that occupies 3600 mm 2 [5], proximity-coupled feed RFID tag antenna with 1838.55 mm 2 [6], Ushaped RFID tag antenna with 2912 mm 2 [7], RFID tag antenna using compact artificial magnetic conductor AMC substrate with total area of 2307.48 mm 2 [8], microstrip patch antenna with EBG ground plane with area of 10000 mm 2 [9], inductively coupled loop antennas with area of 2551.5 mm 2 [10] and bow tie C shape feeding scheme tag antenna which occupies an area of 33000 mm 2 [11].…”

Abstract-The main goal of this paper is to present a design procedure for a flexible compact universal UHF RFID tag antenna suitable for worldwide UHF RFID applications. Systematic design procedure is introduced through the derivation of dipole input impedance general relation using induced EMF method considering wire radius effect. T-matched chart is used to match the tag input impedance with the chip input impedance and finally develop a flow chart to summarize the design procedure. The proposed antenna compactness trend is achieved through applying meandering and Franklin shape to conventional printed dipole antenna. Flexibility trend is achieved through using liquid crystal polymer LCP material as antenna substrate. The proposed antenna covers the frequency band 865 MHz to 1078 MHz and occupies an area of 1306.6 mm 2 . The computed radar cross section RCS and conjugate match factor CMF insure that the proposed antenna structure is easily detectable and achieves acceptable matching level. Power reflection coefficient PRC is computed, measured and good agreement is obtained. Other antenna parameters such as radiation efficiency, gain and radiation pattern are also calculated. The proposed antenna is cheap, flexible and suitable for UHF RFID universal application.

“…Dipole meander line structures have been used for the purpose of size reduction in UHF antennas ([5]- [7], [9], and [10]). The arms of the dipole are commonly folded in order to reduce the height/side dimension of the dipole, while sacrificing bandwidth and efficiency.…”

“…In this paper, the design of a miniaturized, cubic antenna for use as the radiation part of an enclosed sensor in a wireless sensor node is proposed. The concept is based on meander line dipole antenna configurations ([5]- [7]), folded into a cube structure. Due to the optimized positioning of the arms of the dipole and using inductive coupling matching techniques, a matched, isotropic radiator is achieved.…”
