In this paper, a simple microstrip antenna for the radio frequency identification (RFID) applications and wireless local area network (WLAN) is presented. The antenna has two operating bands at 2.45 and 5.8 GHz, which are reserved for RFID applications and WLAN applications. The studied antenna design, analysis and characterization have been performed using CST electromagnetic simulation software. The antenna was analyzed with FR4 substrate. Reflection coefficient, VSWR and directivity results were simulated, presented and discussed. The designed antenna was fabricated on ArlonAD320 dielectric with relative permittivity of 3.2. SMA female connector is used for feeding with characteristic impedance of 50 X. The measured reflection coefficient of the proposed antenna is compared with the simulated one, good agreement is observed. The proposed antenna is simple in design and compact in size, providing broadband impedance matching, consistent omnidirectional radiation patterns and appropriate gain characteristics ([1.5 dBi) in the RFID frequencies regions.

“…RFID is becoming more popular in many modern applications; it is considered one of the most active commercial research fields. Several frequency bands have been assigned to RFID applications: 125-134 kHz, 13.56 MHz, 860-960 MHz, 2.450 GHz (2.4-2.483 GHz) and 5.8 GHz . Several issues are involved in choosing a frequency of operation [1,2].…”

“…Different technologies such as 2G/3G/4G and Long Term Evolution (LTE) are modified and developed for wireless data services in Wi-Fi, WiMAX and Industrial Scientific Medical (ISM) applications with circular polarization. WiMAX covers three different bands for low, middle and high frequencies at 2.5-2.8 GHz, 3.2-3.8 GHz and 5.2-5.8 GHz, respectively [1,2]. Microstrip slot antennas with various shapes are studied for wideband wireless applications for linear and circular polarization and bidirectional pattern [3,4].…”

Abstract-In this letter, a new model of antenna with Jerusalem crosses (JC) as fractal slots for circular polarization applications is designed. The proposed slot antenna has a fractal cross formation with four Jerusalem crosses (JC) to achieve wide bandwidth and a compact size as well as circular polarization. A T-shaped feed line is implemented in the proposed antenna for improving the bandwidth while the interaction of the feed line with cross-shaped slots makes circular polarization. The proposed antenna shows bi-directional pattern and bandwidth at 2.42-3.0 GHz with VSWR < 2, which can be used in WiFi and Bluetooth applications with a gain of 3.5 dBi. The proposed fractal antenna size is 40 × 40 mm, and it is designed and fabricated on an FR-4 low-cost substrate with thickness of 1.6 mm. It is simulated by HFSS full wave software. In addition, the experimental results are presented and compared with the simulation for VSWR, radiation pattern and axial ratio.

“…However, the proposed antenna utilizes probe feeding that results in narrow bandwidth. In [29], a microstrip-fed line used in the circular slot antenna has been reported. However, the bandwidth of the antenna has yet been enhanced for dual-band operation.…”

Abstract-A compact wideband dual-frequency microstrip antenna is proposed in this paper. By employing an offset microstrip-fed line and a strip close to the radiating edges in the circular slot patch, an antenna operating at dual frequency with the impedance bandwidth of 26.2% and 22.2% respectively is presented. By attaching a strip to the radiating edges opposite to the microstrip-fed line, this alters the current distribution and radiation on the antenna at the second resonant frequency. The second frequency is also tunable by varying the lengths of the microstrip-fed line. It is demonstrated that the proposed antenna covers the widebands of UHF and microwave for RFID application. A good agreement is obtained between the simulated and experimental results.
