When battery powered sensors are spread out in places that are sometimes hard to reach, sustaining them become difficult. Therefore, to develop this technology on a large scale such as in the internet of things (IoT) scenario, it is necessary to figure out how to power them. The proffered solution in this work, is to get energy from the environment using energy harvesting Antennas. This work presents a wearable circular polarized efficient receiving and transmitting sensors for medical, IoT, and communication systems at the frequency range of WLAN, and GSM from 900 MHz up to 6 GHz. Using a cascaded system block of a circularly polarized Antenna, a rectifier and t-matching network, the design was successfully simulated. A DC charging voltage of 2.8V was achieved to power-up batteries of the wearable and IoT sensors. The major contribution of this work is the tri-band Antenna system which is able to harvest reflected Wi-Fi frequencies and also GSM frequencies combined in a miniaturized manner. This innovative configuration is a step forward in building devices with over 80% duty cycle.

“…The textile-based mmWave antenna presented by Wagih et al operating at 26 GHz and 28 GHz exhibited an on-body peak gain of 7 dB with 40% efficiency [25]. Aside from the research reviewed above, a few more studies on 5G and mmWave antennas for body area networks [25][26][27][28][29][30] have also shown promising results. A huge wideband array antenna operating at 60 GHz for body-centric communication has been 2…”

A compact 5G wideband antenna for body-centric network (BCN) operating on Ka band has been presented in this paper. The design of the antenna consists of a very simple key-shaped radiator patch with a vertical slot for better impedance matching. The antenna was designed and simulated with the help of the Computer Simulation Technology (CST) Microwave Studio Suite, a well-liked and dependable electromagnetic simulation program running on Microsoft Windows. Free-space simulation produces a resonant frequency at 28 GHz, which falls under the Ka band and 5G’s n257, more precisely n261. The proposed antenna has a size of 1.24 λ × 0.6 λ × 0.153 λ and has a wider impedance bandwidth of more than 20 GHz. The antenna’s gain and radiation efficiency are 3.87 dBi and 70%, respectively, at the resonant point. Further parametric studies reveal that the antenna can be activated in the V-band by increasing the feedline width. The antenna is proposed for the application of BCN. Therefore, a three-dimensional human torso phantom was developed virtually to test on-body performance. The on-body findings of this antenna were resimulated by positioning the antenna in close proximity to the three-layer human body model, where 22.5 dB of on-body reflection coefficient was recorded at 28 GHz. Simulated on-body gain and efficiency were 4.56 dBi and 61.33 percent, respectively. A distance-based investigation was conducted to investigate the impacts of the human body’s presence by positioning the antenna at five different distances from the human torso model. The findings were compared to assess how distance affects its behaviors. The antenna’s gap was kept at 6 mm for the optimum results, which included 4.83 dBi of gain with a 66 percent efficiency and a recorded RL value of about 23 dB. The on-body simulations produced very consistent results with a slight deviation after 26.5 GHz, even though the distance was varied.
