RF Energy Absorption in Human Bodies Due to Wearable Antennas in the 2.4 GHz Frequency Band
(Wiley, 2019-11-19)
Human exposure to electromagnetic fields produced by two wearable antennas operating in the 2.4 GHz frequency band was assessed by computational tools. Both antennas were designed to be attached to the skin, but they were ...
Methodology for determining the threshold distance for estimating the main EM exposure contribution in WLAN
(Elsevier, 2021-05-25)
The location of radiation sources in wireless networks is a key factor to characterize their contribution to electromagnetic exposure levels in order to deploy future networks that account for minimizing electromagnetic ...
Characterizing in-band full-duplex in broadcast communications: From field trials to a loopback channel model
(Elsevier, 2024-04-27)
In-band full duplex (IBFD) communications are a potential solution to spectrum scarcity. IBFD communications offer greater spectral efficiency than traditional half-duplex communications by transmitting and receiving on ...
Wearable Slot Antenna at 2.45 GHz for Off-Body Radiation: Analysis of Efficiency,Frequency Shift, and Body Absorption
(Wiley, 2017-09-12)
The interaction of body-worn antennas with the human body causes a significant decrease in antenna efficiency and a shift in resonant frequency. A resonant slot in a small conductive box placed on the body has been shown ...
Toward fully automated inspection of critical assets supported by autonomous mobile robots, vision sensors, and artificial intelligence
(MDPI, 2024-06-07)
Robotic inspection is advancing in performance capabilities and is now being considered for industrial applications beyond laboratory experiments. As industries increasingly rely on complex machinery, pipelines, and ...
