Optimal Design Method of MIMO Antenna Directivities and Corresponding Current Distributions by Using Spherical Mode Expansion
Maki Arai, Masashi Iwabuchi, Kei Sakaguchi +1
This paper proposes a new methodology to design optimal antennas for MIMO (Multi-Input Multi-Output) communication systems by using spherical mode expansion. Given spatial channel…
Where, When, and How mmWave is Used in 5G and Beyon
Kei Sakaguchi, Thomas Haustein, Sergio Barbarossa +18
Wireless engineers and business planners commonly raise the question on where, when, and how millimeter-wave (mmWave) will be used in 5G and beyond. Since the next generation netwo…
Design and implementation of lighting control system using battery-less wireless human detection sensor networks
Tao Yu, Yusuke Kuki, Gento Matsushita +3
Artificial lighting is responsible for a large portion of total energy consumption and has great potential for energy saving. This paper designs an LED light control algorithm base…
