This paper introduces a new circular monopole antenna with triple-band characteristics for use in both UHF and UWB, which can be integrated into an RFID system reader board. The antenna, designed with a patch and a CPW feed microstrip line, meets the UHF/UWB bandwidth requirements for RFID applications. Simulation and measurement results show that the antenna has a maximum gain of 4.8 dBi and a radiation pattern that covers the full working band. Experiments demonstrate that the UHF-RFID performance of the monopole antenna is comparable to existing commercial solutions.
This paper presents a new circular monopole antenna with triple-band characteristics that can operate in both ultra-high frequency (UHF) and ultra-wideband (UWB) and can be integrated into a radio-frequency identification (RFID) system reader board. The antenna was built with a patch and a coplanar waveguide (CPW) feed microstrip line to meet the UHF/UWB bandwidth requirements for RFID applications. The designed antenna has a size of 70 mm x 60 mm x 0.8 mm. CST Microwave Studio simulations were used to validate the proposed antenna, which had a maximum gain of 4.8 dBi. Furthermore, the designed antenna had a radiation pattern that spanned the full working band. To interact with RFID tags, the antenna was built and installed into the RFID reader board. The simulation and measurement findings showed good agreement. Experiments indicated that the UHF-RFID performance of the monopole antenna was comparable to that of existing commercial solutions.
