摘要
针对无线模块中直立式天线体积大、功耗高问题,提出用微带天线替代传统直立式天线的方法,并讨论了微带天线的工作原理。介绍了中心频率为2.4 GHz微带天线的设计流程。根据需求确定微带天线的材料、形状、类型,用公式和软件计算出天线的尺寸等参数,再在Agilent公司的微波电路仿真软件ADS中建立天线模型并对其仿真,通过优化匹配和调整天线模型,得到最佳的天线参数使其特性符合设计要求。
This paper presents a solution to the shortcoming of large size and high power consumption of upright antenna.The solution uses the microstrip antenna in place of the traditional upright antenna.The radiation principle of microstrip antenna is discussed,and the entire design procedure of the microstrip antenna at frequency of 2.4 GHz is introduced.First,according to the requirements of the materials,the shape and the type of the microstrip antenna are determined,and the size of the antenna is determined according to the formula and software calculated results.And then the antenna model is built and simulated in ADS（Agilent）.Finally the best antenna parameters are obtained through the optimizing and matching in order to make the antenna characteristics comply with the design requirements.
