【摘要】 本文设计了一种基于八木天线结构的准八木型微带天线,利用三维电磁仿真软件(Ansoft HFSS)对天线进行仿真,得到一个符合设计需要的实例,工作频段在4.8GHz-6.5GHz,在中心频率5.8GHz处,峰值增益约为11.6dB,前后比约为21dB。给出了准八木型微带天线的设计过程,并对具体结构和参数的选择对天线性能的影响进行了比较和讨论。更多还原

【Abstract】 In this paper, a microstrip Quasi-yagi antenna based on yagi antenna is designed using a software for 3-D electromagnetic field analysis (Ansoft HFSS), and a result that fits the design requirements is presented. The working band of the antenna is 4.8GHz-6.5GHz, and the peak gain at the working frequency of 5.8GHz is about 11.6dB, the front-to-back ratio is about 21dB. The design process of the microstrip Quasi-yagi antenna is also presented, and the influence of the structure parameters on the performance of the antenna is discussed.更多还原
