This chapter explores a concept for deploying parasitic elements at the receiver site to achieve a multiplexing gain in MIMO systems. The concept is based on a virtually fast rotating directional receiver antenna, which rotates once or several times per symbol interval. The antenna rotation is obtained by using a single active antenna element and multiple parasitic elements. The antenna rotation results in the same spatial multiplexing, which is also obtained by conventional MIMO receivers with multiple active elements.It is shown that the rotating receiver antenna provides a much higher capacity than a single receiver antenna. It is also shown that the virtual rotation idea can suffer from problems due to adjacent channel interference.
