This article describes the fundamental conceptions and theories of RFID technology, UHF RFID and UHF label. This article introduces the composition of RFID system and the distinguishing feature of RFID technology. The composition of the RFID system and the characteristics of RFID technology were introduced. And combined with the actual requirements of the current canned food of military supplies automatic identification, an automatic recognition simulation platform was devised and structured, and the recognition function of UHF RFID anti-liquid labels and common RFID labels were contrasted through the methods of heap and passageway.

RFID sensor networks are the closest technology to configure the ecosystems of internet of things. In this paper, we propose efficient dynamic slot reservation based on shortened queries and time-split responses for RFID tag anti-collision. According to the simulation results, under the circumstance achieving 100% reliability, the proposed algorithm achieves more than 50% increase in tag identification rate per second compared with both a query tree algorithm and an enhanced 16-bit random number aided query tree algorithm.

This paper investigates a compact design of a meandered dipole passive ultra high frequency (UHF) radio frequency identification (RFID) tag for the Pakistani frequency band (865-868 MHz). To reduce the tag size, meandering technique and inductive complex impedance structure was incorporated in the proposed design. The overall dimensions of the tag is 0.108λ0 × 0.063λ0 where λ0 is the free space wavelength at 867 MHz. The tag was fabricated on Rogers FR4 substrate with the relative permittivity of 4.6 and thickness of 1.6 mm. The measured result of the return loss of the proposed tag agrees well with the simulated result. The proposed passive UHF RFID tag has a computed read range of 3.96 for 0.1 W ERP (Effective Radiated Power) which fulfills the criteria of passive UHF RFID read range, i.e., greater than 3 meters and less than 10 meters in a direction normal to the reader.

Chipless RFID has gained prominence due to its application versatility and cost and complexity advantages over traditional RFID. However, chipless RFID tags are typically designed for a specific application instead of being deployable for a multitude of applications. In this paper, a new approach to adaptable chipless RFID tag is proposed that can be optimized for a variety of applications, including materials characterization with tags as embedded sensors. Additionally, the designed approach renders tags that can be interrogated with a linearly polarized probe and achieves bit densities up to 27.57 bits/cm
