摘　　要：针对某些弹体尺寸较小而要求天线尺寸较小,提出一种进一步缩小伞形印刷振子天线尺寸方法。在该天线臂上开缝,形成加载伞形印刷振子天线,从而减小天线的尺寸。使用HFSS三维电磁结构软件仿真表明:通过缝隙加载的伞形印刷振子天线,在工作频率2.7GHz时,其尺寸32mm×18mm,比一般未缝隙加载的伞形印刷振子天线,尺寸缩小约15%。In order to increase the antenna gain and decrease the antenna size,a novel slot-loaded printed dipole umbrella antenna with an coupled feed network was proposed for missile-borne instruments that worked at the frequency of 2.7 GHz.Theoretical analysis and simulation results with HFSS showed that the antenna could achieve the gain of 5 dBi.The relative impedance bandwidth was 3.7%（VSWR≤2）and pattern half-power width was 70°.The dimension of the antenna was 15% less than that without slot loaded antenna.
