摘要

在传统偶极子天线的基础上，设计了一种工作在L和s波段的高增益宽带天线，该天线由一个填充介质的金属圆柱形腔和一对同轴可平衡输入的偶极子贴片组成。利用三维全波电磁仿真进行了仿真和优化。结果表明，在1.67 ~ 2.67 GHz范围内具有良好的阻抗匹配(VSWR<1.5)，相对带宽为46%，在工作频率范围内增益从6.72增加到9.67dB。

A Wideband Cavity-Backed Antenna with Good Impedance Matching

Based on the conventional dipole antenna, a new broadband antenna with high gain working at the L- and S-band has been designed, which is composed of a metallic cylindrical cavity filled with dielectric and a pair of dipole patches fed with balanceable coaxial input. The simulations and optimization have been carried out with three-dimensional full-wave electromagnetic simulation. Results demonstrate that it has a good impedance matching (VSWR<1.5) with a relative bandwidth of 46% from 1.67 to 2.67 GHz, and the gain increases from 6.72 to 9.67dB over the operation frequency range.
