Handset Antenna Layout Effects on Capacity

Abstract

With the advent of Multi Input Multi Output (MIMO) capable modern wireless communications, the design of Multi Element Antenna (MEA) systems in a handset has been and it will continue to be of strong interest. Apart from the usual performance criteria invoked for such a design such as return loss, isolation, radiation efficiency, Envelope Correlation Coefficient (ECC) and impedance bandwidth, the design benefits when the achievable capacity and throughput are also considered here. In this work we study the effect of the handset antenna element layout on the resultant capacity under simple, yet realistic, propagation environment and base station antennas.
