Notas:
A previously published guideline for MIMO antenna
arrays is refuted. The influence of radiation efficiency on diversity
gain and MIMO capacity of wireless communications systems is
investigated through simulations and measurements using a reverberation
chamber. Integrated antennas on a portable device have
efficiencies low enough to disallow typical inter-element correlation
assumptions. Both diversity gain and MIMO capacity depend
on the number of antennas, SNR and efficiency in a complex way.
When the efficiency of antennas is considered, certain system capacity
losses are predicted...
