| 摘 要： | 提出了一种具有40%相对带宽和较高增益的印刷型引向天线,天线采用微带线馈电,加载较长的介质板改善口径场的幅相分布,仿真和实验表明:该天线与传统加载多个寄生振子的方法相比,不影响天线的阻抗带宽,增益也能有较大的提高;通过CST Microwave Studio的电流密度与口面场的仿真结果证明了上述结论,该天线亦可组阵使用.

| Abstract: | A 40% relative bandwidth high gain directional printed antenna was proposed, which was fed by micro-strip line.By loading longer substrate, the distribution of amplitude and phase of aperture field can be improved.Simulation and experiment show that the antenna does not affect the bandwidth of the antenna and the gain can be greatly improved compared with the conventional Yagi-Uda antenna.The above results were proved by the simulation results of current density and aperture field distribution of CST Microwave Studio.The proposed antenna can also be used to form antenna array. |
