	abstract = {In this work, we present a UHF-RFID-based noninvasive sensor to measure the concentration of ethanol in water using the volume fraction of liquids in mixture solutions. The sensing system operates at the UHF band (860-928 MHz). The concentration of ethanol in water affects the dielectric properties of the solution and therefore the antenna sensitivity of the RFID tag. This sensor operates by measuring the change in permittivity of a solution because of the change in concentration of ethanol in water. We propose a flexible RFID-Tag sensor a low-cost alternative to identify the possible sensitivity of tag changes and is able to detect a variation of 25\% in ethanol in 9 ml of deionized water (DI-Water). The solution is useful in avoiding counterfeit ethanol solutions that may be toxic. The experimental setup is inexpensive, portable, quick, and contactless. We present results for ethanol solutions ranging from 25\% to 100\% in a small tube container. {\textcopyright} 2022 IEEE.},

	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{\textquoteright}s size is 80 {\texttimes} 40 {\texttimes} 1.6 mm3. 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. {\textcopyright} 2017, Electromagnetics Academy.

	abstract = {in this paper, a new broadband RFID tag antenna is presented. The antenna has a simple structure and low profile with only one layer of FR4 dielectric substrate and metallization. By choosing a proper dimension of the short dipole and the T-matching network, a good and broadband impedance matching can be achieved. The obtained impedance bandwidth (S11\&lt;-10 dB) across the operating band can reach about 232 MHz (24.57\%) for the UHF band, which is from 860 to 960 MHz The proposed design has an omnidirectional radiation pattern and a simulated flat read range (almost 4.05 m) over the entire RFID bandwidth. {\textcopyright} 2016 IEEE.},
