| 摘 要： | 在已有的三层有耗媒质中的透层天线（ＢＰＡ）电流积分方程的基础上，给出了电流积分方程中的索末菲积分的低频近似解析公式并给出了其物理解释。利用三项式全域电流基函数，求得了透层天线的输入阻抗。采用静态场近似方法，很方便的求出了透层天线在地面的电场分布。

| Abstract: | Based on the current integral equations of a Boundary Penetrating Antenna (BPA) embedded in a three layer dissipative medium, the closed form low frequency approximation of the Sommerfeld type integrals involved in the current integral equations of the BPA had been deduced. The physical interpretation of the closed form formulas was discussed. The input impedance of the BPA is calculated with the three term current distribution assumption (entire domain basic function). Furthermore, a simple quasi static approximation formula was employed to obtain the electric fields on the ground due to the BPA. Finally, a numerical example was given. |
