微带偶极子天线的小型化改进设计
内容简介：基于传统的偶极振子天线的原理和结构特点，结合微带天线的优势，改进设计了一种中心工作频率为2.45 GHz的微带贴片偶极子天线，缩小了天线尺寸。设计过程中使用Ansoft HFSS软件搭建天线的模型并进行仿真。制作的天线利用PNA3621网络分析仪进行了测试，测量结果表明：在2.2 GHz～2.7 GHz频带范围内，天线方向图对称性较好，旁瓣较少，与仿真结果较为吻合，天线输入端电压驻波比和回波损耗较为理想，实现了较宽的频带。
Abstract：Based on the traditional principles and structure characteristics of dipole antenna , combined with the advantages of microstrip antenna, an inproved miniature microstrip dipole antenna which operates at the center frequency 2.45 GHz is presented in this paper.An soft HFSS software is used to construct , simulate the antenna model.The antenna is tested by the PNA3621 vector network meter.Simulation and measurement re-sults show that the antenna has good performance in 2.2 GHz~2.7 GHz frequency range , antenna has good symmetry pattern and less side -lobe, input voltage standing -wave ratio VSWR and return loss RL are ideal , which agrees well with the simulated results.
