摘要
本文以面/面等效源模型建立了描述导体和介质混合结构的散射和辐射问题的电场积分方程,介绍了矩量法求解的方法,并利用此方法对伞形印刷偶极子辐射单元进行了分析。
In this paper, a technique based on surface / surface formulation analysis of electromagnetic radiation and scattering from finite conducting and dielectric structures is presented. For the surface / surface fomulation, the surface covering the dielectric volume is re-placed by. equivalent electric and magnetic currents and the conducting plates by suface electric cur-rents. This technique can be utilized for the analysis of arbitrarily shaped finite composite structures. An umbrella printed dipole radiating element with an integrated microstrip balun is analysed by utilizing this technique. The result shows the radiation field of printed dipole is changed with va-riation of bend angle of dipole. When the bend angle 15?, the maximized 3dB beam width is ob-tained. It is very useful for phased array antennas.
