TL;DR: In this article, specific absorption rates (SAR) determined computationally in the specific anthropomorphic mannequin (SAM) and anatomically correct models of the human head when exposed to a mobile phone model are compared as part of a study organized by IEEE Standards Coordinating Committee 34, Sub-Committee 2, and Working Group 2.
Proceedings ArticleDOI
Inductive and capacitive excitation of the characteristic modes of small terminals
TL;DR: In this article, the authors present concepts for the selective excitation of orthogonal modes of small terminals by inductive and capacitive coupling elements, which can be used to implement an efficient MIMO (Multiple Input Multiple Output) antenna system based on the TCM (Theory of Characteristic Modes).
Journal ArticleDOI
Compact Multimode Multielement Antenna for Indoor UWB Massive MIMO
Dirk Manteuffel,Robert Martens +1 more
TL;DR: In this paper, a compact ultra-wideband multielement antenna (MEA) for massive MIMO indoor base stations is proposed, based on the simultaneous excitation of different characteristic modes on each element of the MEA.
Journal ArticleDOI
Systematic design method of a mobile multiple antenna system using the theory of characteristic modes
Robert Martens,Dirk Manteuffel +1 more
TL;DR: In this paper, a three-port multiple-input-multiple-output (MIMO) antenna system for smart phones based on the selective excitation of orthogonal chassis modes is proposed.
Proceedings ArticleDOI
Design considerations for integrated mobile phone antennas
TL;DR: In this article, a tripleband antenna for GSM/DCS/PCS with a parasitic element to enlarge the bandwidth has been proposed based on the analysis of the board effect on the bandwidth of integrated antennas for mobile phones.
