X波段矩形波导相控阵天线

本文给出X波段矩形波导相控阵天线的研制结果。将该天线作为电磁场边界值问题求解,建立了以孔径切向电场为未知函数的积分方程。经矩法处理后,在DJS-6型电子计算机上得到了数值解。制作了115元的无源小阵列。测量了阵单元方向图,加工了两个H面波导模拟器:HIC14°和HIC29°,进行了测试。宽角匹配介质板和孔径上匹配膜片的参数是通过理论计算和试验调整确定的。理论计算结果与测量结果相近。在8600—9600MHz频段和±60°扫描圆锥体内,天线的输入电压驻波比VSWR<2。

X-BAND RECTANGULAR WAVEGUIDE PHASED ARRAY ANTENNA

The results of an actual X-band rectangular waveguide phase controlled antenna array are given. Using the antenna array as boundary values of electro-magnetic field, a solution of the field equations is made, and an integral equation of the tangential electric feild function of an unknown aperture is established. Through conversion to matrix methods, numerical results are obtained by using the DJS-6 computer. A sourceless small array containing 115 elements was made. The directional diagram of the array element was measured. Also two magnetic H face waveguide simulators: HIC 14° and HIC 29° were made, and experimental tests were performed. The parameters of the wide angled matching dielectric plate and the mateching foil over the aperture were determined by theoretical calculations and experimental results are quite close to each other. On the 8600--9600 MHz band and ±60° scanning spherical cone; the VSWR of input voltage on the antenna is less than 2.
