摘要:

为满足机载系统的需要，给出了共形相控阵天线的分析和设计过程，同时研制了一种高度仅为0.14波长的准八木天线单元。利用三维电磁仿真软件HFSS对天线单元和共形相控阵进行了仿真设计，并研制了一套L频段共形相控阵天线。该天线由天线阵面、波束形成网络和波控器等构成。天线阵面由4个天线单元组成，共形安装在机头上。经实际测试，共形相控阵天线阵面的和波束在扫描范围内增益大于10 dBi，并具有较低的副瓣电平；差波束零深小于-20 dB。

Abstract:

To meet the requirement of an airborne system,the analysis and design process of a conformal phased array antenna is presented,and also the quasi-yagi antenna unit,the height of which is nearly 0.14 wavelengths is designed.The software HFSS is used to simulate the antenna unit and conformal phased array.An L-band conformal phased array antenna is developed,which consists of array antenna,beamforming network and beam controller.Array antenna is realized by 4 antenna units,which is mounted on the conformal structure of plane’s nose.The test results of the conformal phased array antenna show that the gain of sum beam ＞10 dBi in all scanning range,meanwhile the low side lobe is achieved,and null depth of difference beam ＜-20 dB.
