Journal ArticleDOI
Pattern Reconfigurable Cubic Antenna
TL;DR: In this paper, a single-feed reconfigurable antenna for pattern diversity is presented, which can switch between three different radiation patterns which radiate in a 4π steradian range and can receive any incident field polarizations.
Journal ArticleDOI
A New Multi-Sensor Fusion Scheme to Improve the Accuracy of Knee Flexion Kinematics for Functional Rehabilitation Movements
Halim Tannous,Dan Istrate,Aziz Benlarbi-Delai,Julien Sarrazin,Didier Gamet,Marie Christine Ho Ba Tho,Tien Tuan Dao +6 more
TL;DR: A real time quaternion-based fusion scheme, based on the extended Kalman filter, between inertial and visual motion capture sensors, to improve the estimation accuracy of joint angles and shows a better estimation, when compared to inertial measurement units and Kinect outputs.
Journal ArticleDOI
Circular High-Impedance Surfaces Characterization
TL;DR: In this paper, the reflection phase characterization used for rectangular high-impedance surfaces was extended to circular lattices and the effect of mapping a rectangular HIS into a circular one was investigated in order to give some insights regarding the design of such metasurface.
Journal ArticleDOI
Near-Body Shadowing Analysis at 60 GHz
TL;DR: In this article, a numerical model of the fading of a receiver (Rx) located near the user body at 60 GHz in an indoor environment is presented, based on the indoor channel model IEEE 802.11ad.
Journal ArticleDOI
Theoretical and Experimental Investigation of a 60-GHz Off-Body Propagation Model
Theodoros Mavridis,Luca Petrillo,Julien Sarrazin,David Lautru,Aziz Benlarbi-Delai,Philippe De Doncker +5 more
TL;DR: In this article, a fast computation and accurate analytical model for off-body propagation is derived for normal incident plane wave by describing the human body with a circular cylinder, which shows that the total received electric field around the body can be written as a creeping wave in the shadow region and as a geometrical optics result for the lit region.
