柱面微带天线的分析与仿真

Analysis and Simulation of Microstrip Antenna Mounted Curved Surface

为研究微带天线与安装柱形壳体共形弯曲后工作性能变化,以平面微带天线为基础建模仿真了不同曲半径的柱面微带天线结构,将平面、不同曲半径柱面的微带天线仿真数据进行了详细分析比较。结果表明:当平面微带天线弯曲成柱面时,中心工作频率和10 d B带宽均不会受到影响,但xz和yz截面上的增益会受到影响。由此得到矩形微带天线在不同曲半径柱面下工作性能的优劣,为曲面微带天线的研究和实用化设计提供了准确的理论与仿真依据。

In order to research the working performance changes of the microstrip antenna after bending with the conformal cylindrical structure, based on the planar microstrip antenna, modeling and simulation of the different curved radius cylindrical microstrip antenna, making a detailed analysis and comparison of the simulation data of the planar and different curved radius cylindrical microstrip antenna. Simulation results indicate when the planar microstrip antenna is curved, the working center frequency and 10 dB bandwidth is not affected, but the gain of ax and is section is affectedh. hereby obtaining the performance of rectangular microstrip antenna under different radius of the cylindrical. It prevides accurate theoretical and simulation foundation for the study and practical design of a curved surface microstrip antenna.
