In this paper, the optimization of sleeve monopole antennas is studied. The model combining the ground plane with the sleeve monopole antennas is adopted, and the genetic algorithm based on niche is used to design the sleeve monopole antennas. Finally, one practical sleeve antenna with the VSWR less than 3.0 in 110～390MHz frequency band is designed according the analysis above. The results show the accuracy and efficiency of the method.
