“…The four radiant patch elements of the array antenna are printed on one side of the low cost Rogers RT/duroid-5880 (tm) substrate having physical dimensions of (223.9 × 98 × 1.56) mm 3 and powered by a 50 Ω line. The proposed array antenna presents a very high gain and reduced size compared to other array antennas proposed for RFID systems [17][18][19][20]. The advantages of the proposed array antenna are: i. low profile simple structure, ii.…”

Radio Frequency Identification (RFID) is a wireless technology used for tracking a tag attached to an object and uniquely identifying it. In the proposed work, an array antenna that has high gain, good impedance matching, good adaptation, and improved reflection coefficient (S 11 ) at 2.40 GHz for the detection system of objects or living things in motion, has been designed and fabricated. The Fire Resistant RT/duroid-5880 substrate is used for the design purpose of the proposed array antenna. The antenna is an array of four elements with an overall dimension of (223.9 × 98 × 1.56) mm 3 and has a microstrip line feed matched to 50 Ω. The impedance bandwidth achieved by the design is about 120 MHz (2.357-2.477 GHz) at the 2.40 GHz microwave band and has a reflection coefficient, S 11 of about −23.17 dB. The measured gain obtained is around 13 dB. An experimental study of the fabricated prototype of the optimized array antenna is performed and the results verify its good performance.

The design and study of the behavior of antennas adapted to radio-frequency identification RFID tags take on all their importance because they must respond to integration problems and therefore the need to design a structure with minimal dimensions, without however deteriorating their performance. The rise in frequency makes it possible to have short wavelengths so that it becomes possible to have a great integrationas as well as very fast bit rate. But, this induces a smaller range due to the propagation losses according to the model of Friis. In this article, a new patch antenna array for microwave frequency band in radio-frequency identification RFID applications will be presented. The antenna covers the band for the central frequency of 2.45 GHz with better loss characteristics. In addition, the antenna offers a high gain at this frequency. After the digital design of the antenna element, which was carried out using the commercial software CST MWS®, the antenna is printed on an FR4 substrate with a dielectric constant of 4.3 and a thickness of 1.6 mm. The comparison between the simulation results and the measurement results proves that the antenna achieves satisfactory impedance matching and radiation efficiency.

“…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.
