摘要
介绍了宽频带渐变式微带缝隙天线的工作原理、设计参数及其对电性能的影响,设计了一种结构简单的天线形式,给出了该天线工作于S、C频段的结构尺寸以及VSWR、辐射方向图的仿真和测试数据曲线,两者之间有很好的一致性,并对影响天线性能的关键参数进行了误差计算。结果表明:在加工精度可达到的范围内,对天线性能的影响不大。该天线可应用于宽频带单极化、双极化阵列天线单元或反射面天线馈源。
The operating principle and designing parameters of the broadband microstrip slot antenna and its influence to the electrical property are proposed in this paper. A simple form of antenna is designed. The scantling of structure, VSWR, the simulation of the radiation pattern and testing data curve of the antenna operating on S and C bands with a consistency between them. An error calculating to the key parameter influencing the antenna performance is carried through. The results show that the accessible machining precision range will take little influence on the antenna performance. The antenna is applicable to the array antenna element with broadband single polarization and dual polarization or antenna feed source with reflecting surface.
