摘要

本文提出了一种高增益圆柱谐振天线。天线由同轴线馈电。它的工作频率可以通过在天线内部填充不同的介质来调节。通过仿真优化了天线的性能，并制作了天线样机。将测量结果与仿真结果进行了比较，验证了系统的性能。结果表明，该天线在1.28 GHz ~ 1.4 GHz频率范围内具有良好的指向性和增益。内部充水后，天线的工作频率可降至200MHz，相对带宽为11%。

A Design of High Gain Cylindrical Resonant Antenna

A high gain cylindrical resonant antenna is proposed in this paper. The antenna is fed by a coaxial line. Its work frequency can be adjusted by filling different dielectric inside the antenna. The performance of the antenna is optimized by simulation, and the prototype is fabricated. The measurement results are compared with the simulation results to validate the performance. The results show that the proposed antenna has good directivity and gain at frequency range from 1.28 GHz to 1.4 GHz. With internal water filled, the work frequency of the antenna can reduce to 200MHz, with 11% relative bandwidth.
