A sectored antenna system to optimize the distance between adjacent sensors of an array antenna in a CDMA mobile communication system in which success rate of softer handoff and antenna gain is increased and power consumption of terminals may be evenly distributed. In the CDMA mobile communication system, a cell is divided into a number of sectors. A sector antenna system comprising a number of linear array antennas, in which distance between the antenna sensors is determined in consideration of overlapping angle of beams to supply softer handoff is provided. The system also includes carrier demodulators, matched filters, a weight vector estimator, weight vector multipliers, weight vector combiners, parallel demodulators, and a signal combiner.
A sectored array antenna system in a CDMA mobile communication systems with each cell divided by a number of sectors having a plurality of linear array antennas, the system comprising a plurality of antenna sensors, wherein the distance between adjacent antenna sensors is determined by the following equation to supply a softer handoff:
