锥削开槽天线的计算

锥削开槽天线的计算 ANALYSIS oF TAPERED-SLOT ANTENNAS 黄景熙 Huang Jingxi first-author 范治波 Fan Zhibo 本文提供了一种能方便地与微带、开槽线、鳍线等新型微波和毫米波段传输线相集成的天线的理论分析。虽然由于这种天线的一系列优点近年来在国外已被成功地应用于毫米波段,如各种单波束应用和成象阵列系统中,但遗憾的是直到现在只有关于这种天线的较多的实验研究,而无理论分析。本文用谱域法首次计算出这种天线沿端射方向（Z方向）的归一化导波波长（λ′/λ）变化曲线,这就为计算这种天线的其它电性能提供了必要的数据。 This paper presents a theoretieal analysis for tapered slot line antennas which can be easily integrated with microstriplines, slotlines and finlines. Though in recent years, they have widely been applied in ram-wave single beam as well as in imaging systems and have experimentally been investigated, no theoretical approach has been available. In the paper, the characteristic equations for th guide wavelength is derived applying Galerkin’s method in the Fourier domain. The computed results for the variation of guide wavelength against the z-coor,dinate are prescnted to provide the necessary data for the design of these antennas. 鳍线 锥削开槽天线 伽略金法 finline tapered slot antenna Calerkin’s method. 1989-01-01 2021-04-01 1
