摘要: 本文給出X波段矩形波導(dǎo)相控陣天線(xiàn)的研制結(jié)果。將該天線(xiàn)作為電磁場(chǎng)邊界值問(wèn)題求解,建立了以孔徑切向電場(chǎng)為未知函數(shù)的積分方程。經(jīng)矩法處理后,在DJS-6型電子計(jì)算機(jī)上得到了數(shù)值解。制作了115元的無(wú)源小陣列。測(cè)量了陣單元方向圖,加工了兩個(gè)H面波導(dǎo)模擬器:HIC14和HIC29,進(jìn)行了測(cè)試。寬角匹配介質(zhì)板和孔徑上匹配膜片的參數(shù)是通過(guò)理論計(jì)算和試驗(yàn)調(diào)整確定的。理論計(jì)算結(jié)果與測(cè)量結(jié)果相近。在86009600MHz頻段和60掃描圓錐體內(nèi),天線(xiàn)的輸入電壓駐波比VSWR2。

Abstract: 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 wasmeasured. 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. -
