Capacity maximizing MIMO antenna design for Car-to-car communication

The handling of the radio channel is an important aspect that determines the working capability of a mobile communication system. Since the channel behavior is influenced by the environment, which leads to a different behavior in different environment, the antenna design (synthesis) becomes environment dependent (time-variant) as well. In this paper, a capacity maximizing approach to design antenna systems for time-variant channels is presented. Real world constraints such a space, transmit power, the number and arrangement of the antennas are taken into account. The theory of this approach and an optimization of a 2×2 MIMO system for Car-to-car (C2C) communication using measured antennas patter and simulated in typical C2C scenarios are shown.
