On the selection of radiating elements for compact indoor massive-multiple input multiple output base stations

Julien Perruisseau-Carrier

Massive-multiple input multiple output (MIMO) was recently proposed as a key solution for improving the performance of multi-user MIMO in future cellular generations. The main paradigm in this novel MIMO technique is to use a very large number of antenna e ...

Compact UWB antennas for Wireless Body Area Networks (W-BANs)

Anja Skrivervik, Jean-François Zürcher, Jovanche Trajkovikj

A major issue in Wireless Body Area Networks (W-BAN) is the reliability of the transmission in all conditions, thus in all locations and positions of the wearer. One way to achieve this is to design communication systems as independent as possible to the p ...
