摘要: 本文导出了涂覆无耗介质层的无限长金属圆柱结构的并矢格林函数以及与这种结构共形的微带天线辐射场的一般表达式,并利用表面电流模型法研究了介电常数、介质层厚度和金属圆柱体半径对环绕微带共形天线方向图的影响。Abstract: The general field expressions for conformal microstrip antennas on cylindrical body are derived based on dyadic Green s functions for concentric-cylindrical layered media. The radiation patterns for various radii, permittivities, and thickness of the dielectric layer of a microstrip wrap-around antenna are obtained using the general field expressions and electric surface current model.
