It is designed a pair of 5 m whip antenna for antenna arrays, the integrated use of a centralized method of loading and top loading, which is reducing the sensitivity of the antenna impedance versus frequency and using the moment method and genetic algorithm to load the network number so that the location load resistance element can be to optimize the design, and the actual production of the antenna test results are consistent with the simulation results, and the test results show that the antenna VSWR within 5 ～ 20MHz frequency range of less than 2.5.
