摘　　要：介绍一种一体化设计的阵列天线单元。通过对微带辐射振子和Wilkinson功分器的一体化设计,降低了天线的重量,同时展宽了天线单元的驻波带宽。实验结果表明,该阵列天线单元的驻波在15%的带宽内(L波段)小于1.2,满足了实际使用的要求。该设计思路和设计方法具有很好的可扩展性。An integrative design of microstrip antenna unit is introduced in this paper. Microstrip dipole and Wilkinson divider are designed in a piece of microstrip material, which reduces the unit＇s weight and also makes the bandwidth wider. The Experiment results indicate that its VSWR is less than 1. 2 within bandwidth of 15% （at L waveband）. The unit meets need for practical use. The design method can be well extended to other usage.
