摘要
为改善天线性能,利用人工磁导体的工作机理,设计了工作频率在2.4 GHz和5.0 GHz的2种方形贴片人工磁导体结构,并将其加载于一种双频带单极子天线上.HFSS仿真结果验证了设计的可行性,天线的方向性系数从2.3提升为4.4,前后比从2.0提升为20.0,增益提升了2.5 dB.
To improve the antenna performance,the working mechanism of the artificial magnetic conductors is studied in this paper.Two kinds of square patch artificial magnetic conductor structures working at 2.4 GHz and 5.0 GHz are designed.The artificial magnetic conductor structure is loaded on a dual-band monopole antenna to improve antenna performance.The feasibility of the design is verified by the HFSS simulation results.The directivity coefficient is increased from 2.3 to 4.4,the front-to-back ratio is increased from 2.0 to 20.0,and the gain is increased by 2.5 dB.
