Read Range

This paper presents a passive cavity type Ultra High Frequency (UHF) Radio Frequency Identification (RFID) tag antenna having the longest read-range, and compares it with existing long-range UHF RFID tag antenna. The study also demonstrates mathematically and experimentally that our proposed longest-range UHF RFID cavity type tag antenna has a longer read-range than existing passive tag antennas. Our tag antenna was designed with 140 × 60 × 10 mm3 size, and reached 26 m measured read-range and 36.3 m mathematically calculated read-range. This UHF tag antenna can be applied to metal and non-metal objects. By adding a further sensing capability, it can have a great benefit for the Internet of Things (IoT) and wireless sensor networks (WSN).

The system presented in this article has been developed in order to solve several problems occurred during uploading raw materials in the storage tanks of a dry mix mortars plant and to keep an accurate material balance of raw materials introduced in the production process. The proposed approach was to implement a UHF, RFID (Ultra High Frequency, Radio Frequency Identification Device) system consisting of tags on the intake of the uploading pipes and outlets of the transportation trucks and a UHF, RFID Writer/Reader with four antennas in the proximity of uploading and to create an associate database for tracking the uploaded materials. The newly developed system has been successfully operationally tested in a dry mix mortar plant nearby Ploiesti.

System Operating

The development of compact radio frequency identification (RFID) tag is the key requirement for wireless tracking of precious small size goods/packages in transport. A design of compact meander line tag antenna having inductive coupling feed is presented for RFID system operating at ultra high frequency band of865–867 MHz. The size of the proposed tag antenna is43 mm × 10 mm, and is designed using Higgs 4 IC chip (made Alien Technology, USA) having impedance of20.55− j191.45 Ωat centre frequency866 MHz.The antenna characteristics such as impedance, radiation pattern, bandwidth, and effect of ground on gain and tag size are analyzed and found to closely match with the simulated values. The observed value of reading range varies from87.5 to 35 cmsdepending on mounting on non-metal and metal packages, respectively.
