2. 1. Mobile Antenna Systems for 4G and 5G Applications with User Body Interaction

   Author : Kun Zhao; Sailing He; Cyril Luxey; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna; MIMO; mmWave; Mobile communication; SAR; Power density; User body effect; Channel modeling; Multiplex efficiency; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In the thesis, the user body effect on antennas in a mobile terminal is discussed. In order to overcome the degradation of Multiple-Input Multiple-Output (MIMO) performance due to the user body effect, a quad-elements MIMO antenna array which can mitigate the body effect through an adaptive antenna switching method is introduced for 4G mobile terminals.

   Abstract : Overweight people claim to be mistreated by the fashion industry. If they were, it would be in line with branding theory supporting the idea of rejecting fat consumers to improve user imagery for fashion brands. However, fashion companies do not confess to such practices.To shed some light on the subject, I have conducted two studies. READ MORE

   Abstract : The human body is capable of very rich and complex movements and gestures which we use in everyday life to manipulate, navigate and negotiate the world around us—it is our interface for human experience. However, as technology advances it simultaneously shrinks, moving closer to our bodies, intertwining with the many facets of our lives and positions itself between our experiences of the physical environments around us.
