摘要

为了提高偶极子天线的带宽，提出了一种平行栅形偶极子。垂直于偶极子臂方向的行波分量通过栅栏状臂之间的电流耦合而增加，从而减少偶极子上发生的反射。通过CST Microwave Studio®的建模和仿真，在结构尺寸相似的情况下，所提出的平行栅栏状偶极子的相对带宽提高到普通形状平面偶极子的2.4倍，其辐射性能与普通形状平面偶极子相当。

Research on a Method for Effectively Improving the Bandwidth of Dipole Antennas

In order to improve the bandwidth of the dipole antenna, a parallel fence-shaped dipole is proposed. The traveling wave component perpendicular to the direction of the dipole arm is increased by the coupling of current between the fence-shaped arms, thereby reducing the reflection occurring on the dipole. Through the CST Microwave Studio® modeling and simulation, when the structural dimensions are similar, the relative bandwidth of the proposed parallel fence-shaped dipole is increased to 2.4 times that of the common shaped planar dipole, and its radiation performance is comparable to common shaped planar dipole.
