| 摘 要： | 设计了一种采用平衡微带线馈电的具有梯形有源振子的印刷引向天线。对梯形印刷有源振子的阻抗特性进行了仿真，在此基础上进行了改进，首先是有源振子加载反射器，然后是有源振子加载引向器和反射器。仿真了天线的阻抗特性和辐射特性，并分别制作了天线实物进行测试。仿真与实验结果表明，有源振子加载引向器和反射器后的工作频带为2.0~2.45GHz，相对带宽达20.2%，带内增益为6dB 左右，且具有较小的尺寸（60 mm×65 mm），可用于移动通信领域。

| Abstract: | A kind of printed director antenna with trapezoid active dipole is proposed in this paper, which is fed by a balancedmicrostrip line. The simulation of the impedance characteristic of the trapezoid printed active dipole is given above all. Thenimprovements based on this model are presented, first a reflector is added, afterward the reflector and director are added at the sametime. The impedance characteristic and radiation characteristic are simulated, and the antenna is manufactured and measured.Simulation results and measurement results show that the antenna adding reflector and director can operate at 2.0~2.45GHz, and therelative bandwidth will be 20.2%, and the gain will be 6dB within the frequency band. The antenna has smaller size (60mm×65mm),and can be used in the mobile communications. |
