摘　　要：随着无线传感网技术发展,基于ZigBee协议的无线抄表系统得到快速发展。而天线是智能电表终端ZigBee通信模块中影响传输距离重要因素之一。为了满足电表空间小的环境需求,设计了与ZigBee模块一体化的IFA(inverted-F antenna),采用了HFSS软件进行了电磁仿真,用印制板技术与4层结构的ZigBee模块集成在PCB上,并与射频端口实现良好的匹配,提高天线的发射效率。测试结果表明:设计的IFA天线在2.405 GHz到2.483 5 GHz之间S11均小于-10 dB,在2.45 GHz中心频率下,最大增益达2 dB以上,天线具有全向性。With the development of wireless sensor network technology,the wireless meter reading system gets rapid development based on ZigBee protocol.The antenna is one of the most important factors that affect the transmission distance on smart meter terminal ZigBee communication module.For meeting the environment needs of small space,IFA integrated with ZigBee module is designed in this paper,and HFSS software is adopted for electromagnetic simulation,The IFA designed with printed circuit board technology and integrated in the 4 layer structure of the ZigBee module.The IFA achieves good matching with the RF port and improve antenna transmitting efficiency.Measurement results show that the designed IFA has the input reflectivity coefficient S11 of less than-10 dB at the frequency between 2.405 GHz to 2.483 5 GHz.The biggest gain is more than 2 dB at the frequency of 2.45 GHz.
