摘要

介绍了一种用于数字电视广播的宽带发射天线单元。天线单元由四个垂直定向的偶极子组成。采用领结型偶极子代替圆柱型偶极子,实现了天线参数的改善。本文讨论了天线单元馈电网络。最后,对CST微波工作室的模拟天线单元进行了演示,并给出了仿真结果。

Wideband antenna for DVB-T
The paper deals with a unit of broadband transmitting antenna used for digital TV broadcasting. The unit of antenna consists of four vertically oriented dipoles. The improvement of antennas parameter is achieved by replacing cylindrical dipoles by bowtie type. The feeding network of antennas unit is discussed here. Finally, unit of simulated antenna in CST Microwave Studio is demonstrated and obtained results are presented.
