Wang wanghao@mes.tu-darmstadt.de M. Glesner Microelectronics System Institute, TU Darmstadt, Germany Smart antenna systems attract a lot attentions now and believably more in the future, as it can increase the capacity of mobile communication systems dramatically. Design of smart antenna systems combines the technologies of antenna design, signal processing, and hardware implementation. In this paper, a propose of smart antenna structure, as well as some function blocks that have been already implemented in hardware will be presented. Appelbaum,~S : Adaptive Arrays, IEEE Trans.
