摘要
设计了一个用于车载电话的双频共面振子天线。为获得在同轴馈电时天线振子的平衡馈电 ,该设计使用了共面波导馈电结构。仿真计算结果给出了天线振子双臂的电流分布 ,并显示设计的共面振子天线在两个不同的频率上工作。实际设计天线的测试结果表明 ,在两个频带 82 4MHz～ 896MHz和 1 85 0MHz～ 1 990MHz内 ,设计天线的驻波比都小于 2 。
This paper presents a design method of a dual frequency coplanar dipole antenna which can be used as a mobile phone antenna. To obtain the balanced feed for the dipole antenna driven by a coaxial transmission line, a coplanar waveguide fed structure is used. The simulation results present the current distribution of the dipole antenna, and show that the designed coplanar dipole antenna operates at dual frequency. The measured results demonstrate that the VSWR of the designed antenna is less than 2, and the average gain of the antenna is greater than the specification value in the two bandwidths of 824MHz～896MHz and 1850MHz～1990MHz.
