“…Recently, several antenna designs have been investigated for their suitability as antennas for IoT devices. Some of these designs include patch antennas [8–10], planar monopole antennas [11], printed inverted-F antennas [12], and loop antennas [13]. In most of these publications [9–11, 13], however, fractional bandwidths (FBW = (( f H – f L )/ f C ) × 100%, where f L and f H are the lowest and highest usable frequency of the antenna for | S 11 | ≤ −10 dB, respectively, and f C is the center frequency of the operation band) are generally <50%.…”

A flexible broadband antenna with high radiation efficiency for the Internet of Things (IoT) applications is presented. The design is based on a U-shaped and a triangular-shaped radiator with two tuning stubs. A 50 Ω coplanar waveguide (CPW) transmission line is employed to feed the antenna. The proposed antenna is fabricated on a flexible substrate from a composite synthesized by mixing natural rubber with SiO2 as a filler. The radiating elements, along with the CPW, are built using a highly conductive woven fabric. Results show that the antenna has a simulated and measured impedance bandwidth of 0.856–2.513 GHz and covers the most commonly used wireless communication standards and technologies for IoT applications. The radiation efficiency of the antenna reaches over 75% throughout the operating frequency band with satisfactory radiation patterns and gain. The flexible antenna was also tested under bending conditions. The presented results demonstrate that bending has a minor effect on the antenna performance within the target frequency range. The measured results show a good agreement with simulations.

“…The development of wireless communication systems also increases rapidly, hence it is necessary to provide small size and multiband antennas for IoT applications. IoT will provide a platform to allow big data transfer mechanism and communication between people and devices, which provide high quality of life in society [1]. IoT is a worldwide network that provides a platform allowing big data transfer and connection between people and things.…”

This paper presents a novel reconfigurable filtering antenna with three tunable states used for IoT applications. The frequency reconfigurability is achieved using the combination of a hairpin filter and an open loop filter in the structure with the switching of p-in diodes. The open-loop filter structure provides two narrow band states at 2.4 GHz and 7.8 GHz, and the hairpin filter provides a single narrow band state at 10.4 GHz. The frequency reconfiguration is obtained without compromising the compact size of the designed circuit along with the targeted frequency bands at lower WLAN (2.47 GHz), WiMAX (3.42 GHz), INSAT C-band (7.18 GHz), fixed/mobile satellite service in X-band (8.4 GHz), direct broadcast service in Ku-band (12.14 GHz) applications. The prototype is constructed on an FR4 substrate and tested for validation in an anechoic chamber. The designed antenna provides excellent radiation characteristics and considerable gain at resonant frequencies. The proposed reconfigurable antenna is also tested using the CDAC Cmote device in the real-time environment and found more suitable for the IoT based communication applications.

“…All those propositions and other good antennas presented in Ref. present good designs but are based on protruding antennas which cannot be used inside small‐size tracking devices and present a considerable manufacturing cost. None of the current research works proposed a simple low profile and miniaturized design that combines the GPS technology with UMTS/LTE technology.…”

This article presents a novel low-cost integrated multiband antenna design customized for navigation media applications. The distinctive feature of the design consists in using a broadband planar dipole with four arms and a miniaturized feeding-point, easy to deploy inside the tracking devices, and cost-effective for supply chain industry. The article first introduces the main challenges and the benefits of miniaturizing antennas for supply-chain and particularly for navigation media system which is the case-study. Further the parametric study and final dimensions of the design and the simulation results are discussed. The proposed design is fabricated and the measurements of the radiation pattern and the return loss are performed proving that the antenna with maximum gain up to 10 dBi and S 11 up to −30 dB, exhibits excellent performance for all the frequencies required in the navigation media systems such as 1. 6, 1.8, 2.3, 2.4, 2.6, 3.6, and 5.8 GHz. The proposed design was implemented and tested inside a tracking device mounted on a vehicle and compared with existing commercial antennas. This study showed that the proposed antenna is suitable for tracking devices as it is miniaturized for internal integration and it has better 4G and GPS signal detection and low power consumption comparatively with existing commercial antennas.
