“…Apart from them concrete has also a negative influence of propagation of electromagnetic waves by causing their attenuation. Therefore, a decrease in read distance or even a lack of communication between tags and reader are observed for RFID tags mounted near the mentioned materials [16][17].…”

“…The third generation (3G) communication networks (2.1 GHz), the fourth generation (4G) communication network (1.8 GHz, 2.3 GHz, 2.5 GHz in China), Bluetooth (2.45 GHz), and WIFI (2.4 GHz, 5 GHz) have been widely used. Moreover, the fifth generation (5G) communication system will meet the increasing demands of higher data rates, larger capacity, and lower latency in the future, which is expected to promote the prosperity of the Internet of Things [ 2 , 3 ]. The prosperity of 5G will bring more antennas employed in the frequency band below 6 GHz (3.6 GHz, 4.8 GHz in China).…”

Multiple standard communication networks operate in the frequency band of 1.8–6 GHz, which makes lots of antennas available in the limited space. To solve the problem of interference and improve the performance of these antennas, an ultra-wideband (UWB) antenna is presented. It consists of a boat-radiator and a dual C-shape co-radiative ground (DCCRG). One half of the DCCRG plays a role of the ground of a co-planar waveguide fed to the proposed boat-radiator antenna (BRA), while the other half works as a multiple order L-resonant circuit to broaden the lower operating band. Uniform bidirectional radiation is presented with the size of 0.25 λ × 0.375 λ × 0.0063 λ over the frequency band of 1.7–6.3 GHz (115%). The proposed antenna achieves around twice the bandwidth (60%) of the same structured antenna without the structure acting as a multiple order L-resonant circuit. Moreover, the stable boresight gain of 3.6 dBi ± 1.25 dBi is realized over the operating band.

The radio frequency identification (RFID) has emerged Internet of things (IoT) into the identification of things. This paper presents, a low-cost smart refrigerator system for future internet of things applications. The proposed smart refrigerator is used for automatic billing and restoring of beverage metallic cans. The metallic cans can be restored by generating a product shortage alert message to a nearby retailer. To design a low-cost and lowprofile tag antenna for metallic items is very challenging, especially when mass production is required for item-level tagging. Therefore, a novel ultra-high frequency (UHF) radio frequency identification (RFID) tag antenna is designed for metallic cans by exploiting the metallic structure as the main radiator. Applying Characteristics mode analysis (CMA), we observed that some characteristic modes associated with the metallic structure could be exploited to radiate more effectively by placing a suitable inductive load. Moreover, a low cost, printed (using conductive ink) small loop integrated with meandered dipole used as an inductive load, which was also connected with RFID chip. The 3-dB bandwidth of the proposed tag covers the whole UHF band ranging from 860-960 MHz when embedded with metal cans. The measured read range of the RFID tag is more than 2.5 meters in all directions to check the robustness of the proposed solution. To prove the concept, a case study was performed by placing the tagged metallic cans inside a refrigerator for automatic billing, 97.5 % tags are read and billed successfully. This study paves the way for tagging metallic bodies for tracking applications in domains ranging from consumer devices to infotainment solutions, which enlights a vital aspect for the Internet of Things (IoT). Index Terms-Characteristic mode theory (CMT), Internet of Things (IoT), radio frequency identification (RFID) tag antenna, smart refrigerator I. INTRODUCTION he Internet of Things foresees a future in which physical and virtual things can be uniquely identified on a global scale by means of emerging integrated wireless technologies.
