摘要
本文借助全波三维电磁仿真软件软件HFSS首先针基于微带贴片结构的柔性矩形微带天线进行了建模仿真，对以X轴和Y轴为对称轴将天线向内向外弯曲30度和60度两种情况进行了比较，所得结果对于小型化柔性射频天线的设计研究具有重要的指导意义。
论文主要研究了基于微带贴片结构的柔性矩形微带天线的设计和制作，我们在此次研究过程中，采用很薄的Rogers5880材料作为天线的柔性基底。
研究结果表明：在以X轴为对称轴的情况下，向外弯曲能够获得良好的自反射系数值，向内弯曲天线 参数基本不变在以Y轴为对称轴的情况下，不管是向内向外弯曲天线的 参数基本保持不变。
本文的特色：引入厚度极薄的Rogers5880板材作为微带天线的基底。这既能够在保证天线性能要求的同时缩减天线尺寸，也可以使其具备柔性材料可弯折的特点。结合矩形贴片技术以及同轴线馈电方式,，能够有效降低天线的传输损耗，便捷地完成幅度加权,让天线具备稳定的工作性能，同时降低了天线设计的复杂程度。

Abstract
In this paper, HFSS is used to simulate the flexible rectangular microstrip antenna based on the microstrip patch structure. The antenna is bent inward and outward by 30 degrees and 60 degrees in the direction of X axis and ý axis. The results are of great significance for the design of miniaturized flexible RF antenna.
In this paper, we mainly study the design and fabrication of flexible rectangular microstrip antenna based on microstrip patch structure. In this research, we use very thin Rogers5880 material as the flexible substrate of the antenna.
The results show that when the X axis is the axis of symmetry, the self-reflection coefficient can be obtained by bending outward, and the parameters of the inward bending antenna are basically unchanged. In the case where the Y axis is the axis of symmetry, The parameters of the outer curved antenna remain essentially unchanged.
Features of this article:. Introducing the extremely thin Rogers5880 sheet as a substrate for microstrip antennas This can both reduce the size of the antenna while ensuring the performance requirements of the antenna, but also make it flexible with flexible materials. Combining with rectangular patch technology and coaxial feed Way, can effectively reduce the transmission loss of the antenna, easy to complete the amplitude weighted, so that the antenna has a stable performance, while reducing the complexity of the antenna design.
