圆柱共形微带线辐射特性的理论分析

Radiation Characteris of Infinit conducting Strip on the Dielectric Coatd Cylinder

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场的一般表达式。基于该表达式，分析了介质层厚度、介电常数和圆柱半径对圆柱共形微带线辐射特性的影响。

Conformal micrcotrip anten na is a kind of very suitable anten nas for high speed aircrafts,which possesses a low radar croo section.IN this paper ,the general field exprasions for conformalmicrcatrip antennas on cylindrical they are derived based on dyadic Green' s functions for a dielectric coatedconducting cylinder. The effects of dielectric thickness,dielectric constant and cylinder radii on the radiationpotterns of conformal micrcatrip are discussed according to the general field exprcoions. The exprasions arealso ued for analysis of wraporound micrcotrip antennas;
