【摘要】：随着卫星通讯、通信系统的快速发展,平面抛物面天线被广泛的应用。它是基于频率选择表面的滤波特性,通过谐振单元的相位调整机制,可实现大口径多功能的平面天线。本文拟采用时域有限差分(Finite Difference Time Domain,简称FDTD)方法,研究单元种类和单元排列方式对平面抛物面天线特性的影响,从而优化平面抛物面天线的设计,为平面抛物面天线的实际应用提供理论支持。本文通过FDTD方法,研究了电筒型阵元和U-T型阵元对平面抛物面天线特性的影响。平面抛物面天线技术有很好的发展性,因此它具有很好的应用前景。
[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.
