【摘要】：隨著衛(wèi)星通訊、通信系統(tǒng)的快速發(fā)展,平面拋物面天線被廣泛的應(yīng)用。它是基于頻率選擇表面的濾波特性,通過諧振單元的相位調(diào)整機(jī)制,可實現(xiàn)大口徑多功能的平面天線。本文擬采用時域有限差分(Finite Difference Time Domain,簡稱FDTD)方法,研究單元種類和單元排列方式對平面拋物面天線特性的影響,從而優(yōu)化平面拋物面天線的設(shè)計,為平面拋物面天線的實際應(yīng)用提供理論支持。本文通過FDTD方法,研究了電筒型陣元和U-T型陣元對平面拋物面天線特性的影響。平面拋物面天線技術(shù)有很好的發(fā)展性,因此它具有很好的應(yīng)用前景。
[Abstract]:With the rapid development of satellite communication and communication system, planar paraboloid antenna is widely used. It is based on the filter characteristic of frequency selective surface and can realize large aperture multi-function planar antenna through the phase adjustment mechanism of resonant unit. In this paper, the finite-difference time-domain (Finite Difference Time Domain, (FDTD) method is used to study the effects of the type and arrangement of elements on the characteristics of planar paraboloid antennas, so as to optimize the design of planar parabolic antennas. It provides theoretical support for the practical application of planar paraboloid antenna. In this paper, the effects of flashlight element and U-T element on the characteristics of planar paraboloid antenna are studied by FDTD method. The planar paraboloid antenna technology has a good development, so it has a good application prospect.
