【摘要】 智能家居无线传感器系统通常是由室内短距离无线通信模块组成,其传感器节点模块往往具有系统集成度高、体积较小的特点,这也要求传感器节点的天线小型化,以易于系统集成。基于此,本文设计了一款用于智能家居无线传感器的小型化印制天线。天线采用CST电磁仿真软件建模仿真,根据优化后的天线模型参数,最终设计集成在无线传感器印制电路板上印制天线。该天线工作于2.4GHz ISM频段,具有低成本、小型化等优势,适合用于智能家居无线传感器模块。更多还原

【Abstract】 Intelligent Home Wireless Sensor system is usually made of short range wireless communication modules which are highly integrated and have a small size, which requires the wireless communication module antenna miniaturized for wireless sensor system integration. We design a small printed antenna for our Intelligent Home Wireless Sensor system according to the above requirements. The antenna is modeled and simulated by electromagnetic simulation software CST and HFSS, and is printed on the top print circuit board(PCB) of the wireless communication modules. The antenna’s working frequency lies in 2.4GHz ISM band and it has the advantages of low cost and small size for intelligent home wireless communication modules.更多还原
