“…Both implementations of this resonator are diagrammatically represented in Figure 6a. Islam et al [93], Figueiredo et al [94] and Mumtaz et al [95] all used this form of resonator in their tag design. The implementation described in Reference [93] uses slots of this type with a large distance between the prongs and partially back-fills in the ends of the slots with a metallic filling as a means of addressing.…”

Chipless Radio Frequency Identification (RFID) has been used in a variety of remote sensing applications and is currently a hot research topic. To date, there have been a large number of chipless RFID tags developed in both academia and in industry that boast a large variation in design characteristics. This review paper sets out to discuss the various design aspects needed in a chipless RFID sensor. Such aspects include: (1) Addressing strategies to allow for unique identification of the tag, (2) Sensing mechanisms used to allow for impedance-based response signal modulation and (3) Sensing materials to introduce the desired impedance change when under the influence of the target stimulus. From the tabular comparison of the various sensing and addressing techniques, it is concluded that although many sensors provide adequate performance characteristics, more work is needed to ensure that this technology is capable/robust enough to operate in many of the applications it has been earmarked for.

This work involves two technics of MPA (Micro-strip Patch Antenna) radiation characteristics enhancement, firstly by the design of a 1*2 array antenna based on two slotted ones to enhance the gain and the directivity, secondly by the design of the same antenna with modified ground plan (DGS technic: Defected Ground structure). The 1*2 array antenna is feed by a 50-Ohm micro-strip line, set on an Epoxy FR-4 substrate, and designed to resonate at 2,45GHz frequency. Besides, simulation results of this array were performed by HFSS simulator and validated by CST, they were focused on adaptation characteristics (S11, VSWR and bandwidth) and far field radiation characteristics (Gain, Directivity and Radiation Pattern). The final proposed antenna can be used in narrowband indoor positioning application for RFID readers, using a fixedreader-scheme.

“…In RFID systems, antennas are used in Tags and readers and provide an important concern for the detection system of objects. [14][15][16][17]. Many researchers have investigated different microstrip 1×2 array antenna for RFID applications that offers maximum gains of about 4.73dBi [18], 6.6 dBi [19], and 9.36 dBi [20].…”

In this paper, a printed 1×8 array antenna operating at 2.4 GHz is proposed for radio frequency identification (RFID) Reader. The proposed array antenna is composed of eight identical modified patch elements. The radiating elements are fed in parallel via a simple 50 Ohm microstrip line matched with a quarter-wave impedance transformer using a T magic power divider to divide the input power into two equal quantities with the same phase. The suggested array configuration is designed using Rogers RT/duroid 5880 substrate having dielectric constant εr = 2.2, dielectric loss tangent = 0.0009, and substrate’s height of 1.56mm. The overall dimension of the 1×8 array antenna is 117×475mm2. The proposed array antenna shows good impedance matching, high gain and directional radiation patterns. The proposed array antenna has a high gain about of 14.61dBi, high radiation efficiency of 98.3%, and a good reflection coefficient S11 of -13.14dB and voltage standing wave ratio (VSWR) of 1.56 at 2.4 GHz.
