This paper presents an improved method to isolate
the ports for a MIMO antenna in hand-held devices using
lumped components. It has been analyzed through simulation and
measurement. The total efficiency and the envelope correlation
have been evaluated.
Compared to the case with no decoupling mechanism, the
efficiency from the scattering parameters increases significantly
and the envelope correlation coefficient decreases dramatically.
Nevertheless, when choosing the components, the ohmic losses
must receive extra consideration in order to maximize the system’s
total efficiency. Furthermore, the use of lumped components
has the potential to make the presence of other components in
the mobile device or the user, less harmful to the decoupling
