摘要
基于腔模理论和等效原理推导出环绕式微带共形天线远区场的表达式。根据该表达式算得的TM_(01)模天线方向图在相对介电常数较小时与文献〔3〕的结果相吻合。同时还研完了圆柱半径对天线方向图的影响。
An analysis of a thin wraparound microstrip antenna ispresented.Based on the cavity model and the equivalence principle,for-mulas are obtained for the far-zone electric field by considering theequivalent magnetic current radiating in the presence of a cylindricalsurface.For small values of the relative permittivity ε_(?),the radiationpatterns for TM_(01),mode are in agreement with those of [3].Finally,graphical,results are given to illustrate the effects of curvature on theradiation patterns.
