The advent of context-aware environments and related applications demands a high degree of connectivity, with new spectral bands and related radio resource management functionalities in the current 5G bands and foreseen in future 6G wireless communication systems. This, in turn, poses new challenges in the implementation of wireless transceivers and radiating systems, in terms of device integration, miniaturization and element isolation, among others. High-performance miniature devices are presented and studied in this work, aided by metamaterial-inspired complementary resonators. A single particle is used to build a single layer, double layer, double frequency resonators and power dividers. A complete characterization of each equivalent circuit is also analyzed, showing great agreement between analytical circuit models and full-wave electromagnetic simulations. By adding more particles, different diplexers and triplexers in the multi-layer configuration are proposed. The flexibility in the design is the key advantage, as all devices are easily tunable and the output lines can be built in different layers, enabling frequency scalability from RF to millimeter wave ranges. Nevertheless, they are only a sample of all possible combinations of devices that can be designed for integration in future wireless communication systems.

“…So, these conventional tags are orientation sensitive and cannot be readable in all orientations. Also, it is common to use circularly polarised reader antenna to avoid orientation problem of linearly polarised tag at the expensive of 3dB loss due to polarisation mismatch, which reduces read range of RFID tags [1][2][3][4][5].…”

This paper presents a circularly polarised RFID tag antenna using characteristic mode analysis. The proposed design consists of a leaf-shaped radiator with two cross slots and shorting stubs etched on a grounded FR4 substrate. By analyzing the characteristic modes, the diagonal slots are created at suitable locations to enable modes to resonate in the required frequency band. In addition to this, edge rounding is perfumed to create modes with orthogonal current distribution for circular polarisation. Moreover, the RFID chip is placed as a capacitive coupling element at current minima to excite these orthogonal modes. Furthermore, the tag parameters are optimized to give a conjugate match with Alien H4 RFID chip in US UHF RFID band (902-928 MHz). The proposed tag provides a read range of 3.5 m and 5 m after mounting on low permittivity substrate and 100 x 100 mm 2 metallic plate, respectively.

In this paper, a compact, broadband linearly tapered meandered monopole tag antenna for UHF-RFID is designed and optimized using particle swarm optimization (PSO) algorithm. An inductive T-match network is utilized for impedance matching with capacitive Higgs-4 chip. The optimization goal of PSO was conjugate matching and in consequence the maximization of read range. Equivalent circuit of the proposed tag antenna is derived using ADS software to validate its impedance characteristics. The performance of the proposed tag in terms of tag power sensitivity, read range, realized gain, and differential radar cross section has been experimentally characterized. To check the tolerance of the designed tag to various object platforms, its read range performance is also verified on objects like wood, fiber, plastic, and so forth. Furthermore, read pattern of the proposed tag has been measured and found to have figure of eight in E-plane and omnidirectional in H-plane. Experimental results reveal that the proposed tag covers 865-867 MHz (ETSI band, Europe) and 902-928 MHz (FCC band, United States) both major RFID bands with a read range of 10 and 12 m, respectively. The proposed tag has 2060 mm 3 of volumetric size with maximum measured readable distance of 12 m with EIRP of 3.28 W.
