In this paper, we present a broadband flexible RFID sensor tag antenna to detect the concentration of aqueous solutions. The proposed RFID tag antenna sensor with a T matching network is based on a printed dipole whose arms are loaded with circular disk patches. The structure is printed on a Kapton polyimide flexible substrate. The sensing mechanism of the RFID tag antenna is based on the change of sensitivity of the RFID tag antenna that occurs with the variation of aqueous solution concentration. The proposed sensor is designed using CST Microwave studio, and its various parameters are optimized in order to have a broadband impedance matching that covers the entire RFID band . The experimental setup is small, rapid, contactless, and inexpensive. Results are presented for NaCl and sugar aqueous solutions with concentrations ranging from 0% to 80%.

“…Next, we measure, in an anechoic chamber, the reading range, which is the most important characteristic, to get an understanding about the practical performance of the proposed RFID tag antenna. The theoretical reading range can be obtained using Friis free space equation formula [3]:…”

“…In a passive back-scattered RFID system, the reader transmits a modulated RF signal uniformly in all directions, and the tag, situated within the read-zone of the reader, receives the RF signal and generates a backscatter with identification data to the reader. A passive UHF-RFID tag usually includes an antenna and an RF chip which has a memory to store identification data [3]. For UHF-RFID systems, the input impedance of the RFID chip must be conjugately matched with that of the antenna impedance to achieve maximum power transfer.…”

Abstract-In this paper, we report a single layer modified T-shaped dipole antenna for UHF-RFID tag applications. The designed RFID tag antenna consists of a pair of T-shaped dipole strips loaded with four half discs patches and a tag chip placed in the center. The antenna's size is 80 × 40 × 1.6 mm 3 . Performance of the proposed design was investigated with simulations and measurements. The main feature of this design is that the RFID tag antenna can operate effectively at 868 MHz and 915 MHz frequency bands which make it broadband. The maximum reading range measured in an anechoic chamber is 4.25 m and 5.27 m at 915 MHz and 867.5 MHz, respectively. Furthermore, the RFID tag antenna can work on metallic plates when inserting a foam spacer between them. The final result has a simple configuration, low profile and can be suitable for practical applications dealing with free-space and metallic objects.

“…It can be divided into two categories: active (with an onboard source of power, like a battery) or passive (without battery). Passive tag usually incorporates an antenna and an RF chip which has a memory to store distinguishing data [2]. The input impedance of the RFID chip must be conjugately matched with that of the antenna impedance to accomplish maximum most extreme power exchange [3].…”

In this work, a novel passive tag antenna has been designed, investigated and proposed for UHF RFID applications. It has a small size and can operate in the North and South American band (902-928 MHz). The proposed antenna was etched on a low-cost FR4 substrate with an overall size of 54 × 24 × 0.8 mm 3 in order to be applied as UHF RFID tag antenna at the center frequency of 915 MHz. It consists of embedded Π-match, meandered arms, and an RFID chip placed at the center. The meander line technique is used to assure the miniaturization and the Π-match technique to have a good impedance matching. This antenna has a good reflection coefficient and good read range.
