【 摘 要 】

In this paper, the genetic algorithm is used as the optimization algorithm in real frequency technique for antenna wideband matching. A broadband matching network for an inductive whip antenna is designed by using genetic algorithm to optimize the dividing point impedance function, and the dividing point admittance function is optimized for a capacitive monopole. The achievable matching circuits are simulated by ADS and the results agree well with the optimized ones. Simulated results show that the matching networks increase the bandwidth of the antennas, verifying the effectiveness of the technique.
