“…Radio frequency identification (RFID) technology is a wireless communication that employs radio waves to exchange the information between a tag and a reader for tracking and identification purposes. Nowadays, RFID in ultra high frequency (UHF) becomes a very popular technology used in several applications, such as access control system and supply chain management [1,2]. Generally, an RFID system comprises an RFID tag with a chip and RFID reader device.…”

A compact wideband circularly polarized (CP) square slot antenna for universal ultra high frequency (UHF) RF identification (RFID) handheld reader applications is proposed, fabricated, and tested. The antenna is coplanar waveguide (CPW) fed by an inverted Z-shaped feeding line. By inserting four stubs in diagonal directions and two inverted T-shaped strips inside the square slot, broadband CP operation, wide axial ratio bandwidth, and good impedance matching are achieved. The measured < −10 dB impedance bandwidth is from 706 MHz to 1007 MHz (301 MHz, 35.1%). The measured 3-dB axial ratio (AR) is 427 MHz (745-1172 MHz, 44.5%). The maximum measured gain of the proposed antenna is 4.8 dBi. The proposed antenna has wide impedance bandwidth, wide axial ratio bandwidth, and small size. The dimensions of the antenna are only 120 × 120 × 1.6 mm 3. The impedance bandwidth and AR bandwidth performances of the proposed antenna can easily cover the UHF RFID band as whole.

“…However, due to the limited bandwidth and large structure, microstrip antennas are not suitable for some applications. Hence, it is desirable to design small low cost, low profile antenna for simple production process [6]. According to Marrocco [2], the layout of the T-match has a considerable effect on the impedance of antenna.…”

A miniaturized meandered dipole antenna for UHF RFID tag is proposed. Different resonance frequencies and impedance can be achieved by adjusting the number of the meanders, which can help to reduce the size of the antenna. Due to the radiation patches, the input impedance of the antenna can be flexibly tuned in a large scale. The proposed antenna is printed on polyethylene (PET) substrate with a total volume of 48 mm × 13.7 mm × 0.5 mm. Modeling and simulation results show that the reflection coefficient of the antenna is less than −15 dB at 860–960 MHz. Experimental studies demonstrate that the minimum threshold power of the antenna is between 23 and 26 dBm and the measured read range is 3-4 m.

“…However and despite the aforementioned ISO standard, licensed UHF RFID operating frequency bands are allocated within the 860 to 960 MHz band, depending on the geographical region, as for example, ETSI band (865-868 MHz) in Europe, FCC band (902-928 MHz) in North and South America, 920.5-924.5MHz in China, and 917-923.5MHz in Korea and also Japan [14]. The RFID reader antenna is one of the essential constituent elements of an RFID system and its capacity will specify the performance of entire system [15]. The performance of such systems is directly linked to the target application's type and to the antenna's characteristics (shape, dimensions, type of metallization, etc.).…”

In this research work, a novel compact antenna with rectangular slots is presented for radio frequency identification (RFID) handled applications in the ultrahigh frequency (UHF) band that can be manufactured and integrated into RFID readers without difficult. A prototype demonstrating the aforementioned features was constructed and measured. The proposed antenna is fed by 50-Ω coaxial cable and printed on a 1.6mm thick FR4 substrate which has a small size and occupies a volume of 68×66 ×1.6mm3. The patch, the feed-line and ground plane are made of PEC (Perfect Electric Conductor) with a thickness of 0.035 mm. Measured results indicate that the proposed antenna has a good impedance matching characteristic ranging from 889 to 939MHz, which covers the USA RFID-band (902–928MHz), the Chinese RFID-operating-band (920–924.5MHz), and the Korea and Japan RFID-band (917–923.5MHz). These results were achieved by the insertion of slots in the compact structure of the antenna. The electromagnetic simulators HFSS (High Frequency structure simulator) and CST (Computer Simulation Technology) microwave studio were used for the design, modeling and simulation of the antenna. The focus of the study of our antenna was on the parameters of return loss, bandwidth, Voltage Standing Wave Ratio (VSWR), input impedance and gain.
