Abstract
This research proposes a system board of integrated antenna scheme of near-field communication (NFC) and dual band ultra-high frequency (UHF, 920–925 MHz)/2.45 GHz radio frequency identification (RFID) reader antennas for Internet of Things (IoT) applications. The integrated antenna scheme is capable of simultaneous execution of NFC and UHF RFID functions whereby the NFC and UHF RFID modules, which are serially connected to a microcontroller with Wi-Fi module (NodeMCU), read the universal identification (UID) of NFC and UHF RFID tags. The data are then forwarded to a cloud server via Internet of Things (IoT) and are viewable on smartphones using Blynk mobile application via IoT. To realize the optimal antenna design, simulations were carried out using CST Studio Suite. Prototype antennas were subsequently fabricated and integrated into the system board for IoT-linked near- and far-field communication. The simulation and measured results are in good agreement. The NFC reader antenna resonates at 13.56 MHz, and the dual band UHF/2.45 GHz RFID reader antenna achieves the 920–925 MHz and microwave (MW) bands with high isolation. The novelty of the proposed integrated NFC and UHF RFID antenna scheme lies in the use of cloud technology to store real-time and archival data, in place of traditional servers. The integrated antenna scheme could achieve the NFC, UHF, and MW frequency bands, rendering it ideal for IoT applications.
Highlights
Near field communication (NFC) is a short-range radio frequency identification (RFID)-based wireless communication technology for data exchange via contactless data transmission at 13.56 MHz
Ultra-high frequency (UHF) and 2.45 GHz RFID technologies have been deployed in a multitude of applications because of their long-read range and high data transmission rates
In [2], the NFC square coil antenna was fabricated on the opposite side of the UHF RFID reader patch antenna for mobile phones
Summary
Near field communication (NFC) is a short-range RFID-based wireless communication technology for data exchange via contactless data transmission at 13.56 MHz. In [16], a compact 0.92/2.45 GHz dual-band directional circularly polarized (CP) microstrip antenna was proposed for handheld RFID reader applications. In [17], a dual-band circularly polarized antenna was designed and implemented for UWB/UHF RFID applications. In [35], the authors proposed a metamaterial transmission line structure to enhance the gain and radiation efficiency of antennas for multiple wireless communication applications. This research proposes an integrated NFC and dual band UHF/2.45 GHz RFID reader antenna scheme for IoT applications. The integrated antenna scheme is proven ideal for IoT applications as it could achieve the NFC, UHF, and MW (2.45 GHz) frequency bands.
