A smart antenna bed on equal side-lobe Pencil patterns was proposed in this Paper. For comparing withsmart antennas which employ adaptive algorithm

the capacity enhancement of both smart antennas in CDMA system is evaluated. The simulation result show that the adaptive algorithm das not have to be employed. Smart antennas with equal sidelobe pencil patterns has almost the same capacity enhancement Performance. Merits of equal side-lobe pencil Pattern smart antennas are without iteration

faster response and better robustnase.
