“…Obviously, the aim of designing a rectenna is maximizing its RF/DC conversion efficiency given the randomness of the amount of recoverable power. For this, some research proposes solutions allowing to increase the power captured by the antenna; this through the design of higher gain omnidirectional antennas [12] [13]. Other research focuses on the design of HF filters that allow matching between the antenna and the RF/DC converter [14].…”

The abundance of telecommunications systems makes it possible to have somewhat significant quantity of radiofrequency energy in the environment. This energy can be recycled to power ultra-low-power devices such as Wireless Sensor Network (WSN). In this paper, the performance of a miniature RF/DC converter is evaluated in order to enslave a WSN's performance to the amount of the recovered energy. More precisely, a highly sensitive and efficient rectifier is designed to achieve optimum performance in the GSM band. The design method relies on a judicious choice of the rectifying diode which is the basis of most losses in a rectifying antenna (rectenna). Optimum performance is achieved by using the gradient method search proposed in the Advanced Design System (ADS) software. A rectifier based on Schottky diodes HSMS 2850 used in a voltage doubler topology is thus obtained. A maximum RF/DC conversion efficiency of 36% is reached for an RF input power level of 10 dBm. An energy budget of a sensor node in a WSN having an equitable distribution of network loads is then defined and used to evaluate the performance of the WSN regarding the distance at which the Base Station (BS) can be located. The Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is used for this purpose. The distance separating the WSN from the BS is used as the enslavement parameter. Our analysis shows that increasing the duration of each round results in an increase in the range of the WSN. As an example, a network with 100 nodes distributed over an area of 2 100 100 m × may be located at 1.3 km from the base station when each node of the WSN must perform measurements every 1 min.

“…CRLH TL and U‐shaped slots for SIW‐based antenna 14 and the addition of metasurfaces 15 with the same concept is proposed for the Ku, C, and S band, respectively. Kaur and Sivia 16 discussed the design of a plus‐shaped slotted fractal antenna array by combining the fractal antenna and antenna array that operates at multiband for the S, X, and C band applications. Moreover, very few of the antennas are covering the sub‐6‐GHz band which is very much needed as the latest 5G antennas will work in the sub‐6‐GHz bands.…”

Summary In this article, a split‐ring resonator‐inspired fractal antenna for the GSM and sub‐6‐GHz 5G applications is presented. The antenna geometry uses a combination of square‐shaped split‐ring resonators arranged in a Sierpinski fractal arrangement that is realized on a low‐cost FR4 substrate. The overall dimension of the proposed antenna is 0.35λ × 0.35λ mm2 (lowest frequency). The antenna resonates at a dual‐frequency band spanning from 1.75 to 2.0 (13.36%) and 3.01 to 4.18 GHz (33.42%) with a peak gain of 1.5 and 2.05 dBi at respective resonant peaks that correlate satisfactorily with the measured values. The proposed antenna uses Sierpinski fractal geometry on the top and the partial ground plane at the back with dipole‐shaped radiation patterns, and an efficiency of around 80% makes the antenna commercially suited for the GSM and sub‐6‐GHz 5G communication applications.
