摘要: |
单极天线安装在理想导电平面屏上,屏上刻有有限深度的环形缝。将单极天线上电流及缝和自由空间交界处的等效磁流作为未知函数,建立了一对耦合积分方程。从方程得到电流和磁流的数值解。从这些电流和磁流计算了输入阻抗和辐射方向图。 |

Radiation Characteristics of a Monopole Mounted on a Conducting Planar Screen Cut with an Annular Slot of Finite Depth |

Abstract: |
A monopole is mounted on a perfectly conducting (PEC) planar screen of infinite extent in which an annular s1ot of finite depth is cut. A pair of coupled integral equations are derived for this configuration. The electric current on the monopole and the electric field (or equivalent magnetic current) at the interface between the slot and the half space are determined as the solution of these integral equations. The input impedance of the monopole and the far field pattern are computed from these electric current and equivalent magnetic current. |
