Synthesis Of Nommiformly Spaced Linear Array For Gsm/Dcs/Wcdma Base Station Application Using Genetic Algorithm

The design of nonuniformly spaced linear array suitable for GSM/DCS/WCDMA base station application is presented. In the design, both the interspacing between array elements and the feeding Wilkinson power divider for tri-band antenna array are facilitated using genetic algorithm. The simulation results show the nonuniformly spaced linear array fed by an 8-way Wilkinson power divider is suitable for a tri-band antenna array design. And the performances of radiation patterns and impedance bandwidth meet the specifications of base station antennas.
