测量了放置在周期性结构反射表面上方的水平偶极子天线的阻抗。为了直接在其馈电点处表征天线，建议了一种测量技术，其中馈电网络的影响被消除。详细讨论了反射面对偶极子阻抗的影响。此外，还定量地研究了低剖面偶极子的辐射方向图和总效率。
The impedance of a horizontal dipole antenna placed closely above a periodically structured reflective surface was determined. In order to characterize the antenna directly at its feed point, a measurement technique is suggested where the influence of the feed network is eliminated. Implications of the reflective surface on the dipole impedance are discussed in detail. Furthermore, the radiation pattern and the total efficiency of a low-profile dipole are investigated quantitatively.
