摘　　要：针对ZigBee室内定位设备对电磁场高效产生和准确测量的要求,分析了室内定位设备中天线与射频接口电路设计的基本需求,给出了一种倒F型1/4波长单极子PCB板上天线及相应射频接口的分析设计方法。通过电磁场仿真软件Ansoft HFSS及射频电路仿真分析软件ADS2011对天线进行仿真,得到天线的关键参数仿真结果。在实际应用系统中的测试结果证明,天线及其射频接口能够较好地支持定位设备与定位算法的工作,且满足定位节点设备对体积与成本方面的要求。According to the high requirement of mobile location devices thatelectromagnetic field should be generated efficiently and measured accurately, in this paper, basic requirements of antenna and RF interface design are analyzed and a design of a PIFA quarter wave monopole PCB onboard antennaand its RF interface is proposed. The key parameters of the PIFA antenna is presented in the simulation results carried out by Ansoft HFSS and ADS2011. Employed in practical application system, the antenna thoroughly meets the performance, size and cost requirements.
