The individual can simply independent use or as a paraboloid antenna of feed, also can use multiple the composition antenna array. Two arms equal vibrator called symmetric oscillator. Each arm length for one-quarter wavelength and one-half wavelength stretches for half wave oscillator, says the symmetric oscillator. Balance is the balance of converter, imbalance of English. Symmetric type of balance, and feed antenna coaxial cable of unbalanced transmission. If be connected directly with the antenna axis, the center has high frequency current through the skin, it will affect the radiation orientation graph (antenna cable shielding layer of skin also participated in the antenna of radiation). Therefore, in the feed antenna and balance between join with the axis of the converter, the imbalance of the skin with axes flow, high frequency current restrains the truncated. This article primarily describes HFSS emulation software, development process, design environment and basic operation procedures, examples of symmetric antenna design principle and realization symmetrical HFSS simulation software only feed institutions of arms and modeling, then introduce port and boundary setting, reflection coefficients and the far field of 2d simulation results. Keywords: Symmetric antenna, HFSS, simulation 目录 声 明 I 摘 要 II Abstract III 1 引言 1 2 HFSS仿真软件介绍 1 2.1 HFSS软件发展历程 1 2.2 HFSS软件设计环境 2 2.3 HFSS软件基本操作 3 3对称振子天线的设计与仿真 4 这里添加对称振子天线的结构、工作原理等相关内容。 4 3.1设计原理 4 3.2仿真部分 7 3.2.1 建立新的工程 7 3.2.2 设置求解类型 7 3.2.3 设置模型单位 8 3.2.4 设置模型的默认材料 10 3.2.5 创建对称振子模型 10 3.2.6创建波端口 15 3.2.7创建辐射边界 16 3.2.8创建地板 17 3.2.9辐射场角度设置 17 3.2.10求解设置 18 3.2.11保存工程 18 3.2.12求解该工程 18 3
