“…The bandwidth is 270 MHz, and return loss at resonant frequency is -35.3 dB with gain up to 7 dBi. Xing et al [27] presented a dual-band RFID antenna for 0.92 GHz UHF near-field RFID antenna with far-field circularly polarized radiation at 2.45 GHz. The gain of the circularly polarized antenna is about 4.5 dBi and the bandwidth of 110 MHz.…”

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.

“…Multiband operation of the antennas minimizes the number of antennas in the wireless communication systems. In [13], a dual band antenna is proposed for the 0.92 GHz near field and 2.45 GHz far field applications. The designed antenna shows a strong magnetic field for the 0.92 GHz near field applications and the circular polarized field for the 2.45 GHz far field applications.…”

In this article, a triple band microstrip antenna is designed and developed. The rectangular patch is loaded with slots and the ground is made defective for achieving triple band operation. The proposed design is optimized and simulated using CST microwave studio simulator. The optimized structure of the proposed design for triple mode operates at 1.2 GHz, 2.45 GHz and 5.6372 GHz. The prototype of the proposed antenna is developed and measured. The simulated and measured results are presented. Various antenna patterns such as reflection coefficient, E-plane and H-plane radiation patterns, gain, directivity etc are presented and discussed. The reflection coefficient plot of the proposed antenna both in simulation and in measurement confirms the triple band characteristics. The maximum gain and maximum directivity of the antenna are 6.307 dB and 7.279 dBi, respectively. The proposed antenna is suitable for wireless video transmission, wireless security systems, industry, scientific and medical (ISM) radio, and wireless local area networks (WLANs) applications.

“…Recently, UHF and ISM bands have become more attractive because of their suitability for long-range applications and reconfigurability [1][2]. The dual-band antennas developed conform to various communication protocol standards and established operating frequency bands in one system [3][4][5][6]. For that reason, more designs of dual-band antennas for RFID readers were developed to fulfill the requirement of the RFID industry.…”

<p>This paper focuses on the design and fabrication of dual band antenna for UHF RFID and ISM RFID applications. The U-shaped patch loaded with dipole is introduced and investigated. The antenna can be performed dual-band frequencies at 0.915 GHz and 2.4 GHz required in RFID applications with reflection coefficient is less than -10 dB. The lower band can be varied by adjusting both dipole arms length and upper band is tuned by U-shaped patches. The gains of the design with a size 130 45 1.6 mm3 are performed 1.89 dB and 3.65 dB for single and dual band respectively. This compact and low cost dual band antenna also performed total efficiency greater than 80%. The design methodology and antenna measurement results are both presented and discussed in this letter.</p>
