Abstract :
Influences and characteristics of antennas are usually neglected in multiple-input multiple-output (MIMO) system simulations, but are important for the modeling of realistic transmission channels. The paper shows how antennas influence MIMO channels and presents a comparison of spiral and dipole antennas in MIMO systems. The comparison is based first on measurements and second on a stochastic channel model for MIMO channels. It is shown that the pattern of the single antenna elements strongly influences the MIMO capacity.
