A Novel Design Methodology to Realize a Single Byte Chipless RFID Tag by Loading a Square Open-Loop Resonator With Micro-Metallic Cells

Abstract

In this paper, a unique structural design methodology for chipless radio-frequency identification (RFID) tags in frequency domain is presented. The tag geometry is developed by loading an open-loop resonator with micro-metallic-cells (MMC). The realization give rise to a checkerboard resonator type with electromagnetic signatures in its radar cross section that are extremely efficient to manipulate. The resonators layout is distributed on either side of a Rogers substrate to double its coding density. The proposed chipless RFID tag has a memory of 8-bits in total. The operating band of the tag is 6.5-10.5 GHz. The tag has a high bit coding density of 10.94 bits/cm 2 and spectral efficiency of 2 bits/GHz. The tag has a very compact size of 17.4 × 4.2 mm 2 . The simple structuring methodology and efficient resonators layout will give RFID system designers the flexibility to apply the proposed tag in a wide range of modern applications.INDEX TERMS Chipless radio frequency identification (CRFID), frequency-domain (FD), miniaturization, open-loop, radar cross section (RCS), resonators, tag.

“…The tag operates between 6.5 through 10.5 GHz. RFID designers will have the capacity to use the suggested tag in a variety of contemporary applications thanks to the straightforward structuring approach and effective resonance areas arrangement [12]. In this Sun et al article,Data about employee attendance has long been crucial to business management.…”

A Semi-Octagonal 40-Bit High Capacity Chipless RFID Tag for Future Product Identification

“…Frequency-domain-based high-capacity tags were recently presented [29] having a closed-loop structure and [30] a 32-bit single quadrant anglecontrolled tag. In [31,32], a novel design methodology to design CRFID tags via systematic loading of a square split ring with circular and square slots are presented.…”

High-Capacity Double-Sided Square-Mesh-Type Chipless RFID Tags

“…Electromagnetic signatures from the tag are used to decode the encoded information [1]. Many advantages make this technology superior to the conventional chip-based RFID system, such as its low-cost, reduced tag size, lack of line-of-sight requirements, longer life span and direct printability [2,3]. CRFID tags are divided into two main categories based on the design methods: (1) semi-passive and (2) fully-passive.…”

“…Moreover, tags with dual-polarized features have been recently presented. These tags include L-shaped resonators [20] with a code density of 9.45 bits/cm 2 and nested square loop resonators [21] with a code density of 12 bits/cm 2 . A miniaturized open-loop resonator with a tag size of 6.6 × 10.8 mm 2 with a high code density of 4.99 bits/cm 2 using a very complex optimization technique was discussed in [22].…”

“…This paper presents a frequency domain RCS-based chipless tag using a novel design methodology. The tag is composed of square open-loop resonators with a size of 3.8 × 3.8 mm 2 . The open-loop resonator is sequentially loaded with small square metallic patches to systematically produce resonances at different frequencies.…”
