摘　　要：在室内环境下的射频定位系统的探测器设计中,天线波束须满足宽波瓣的条件对房间进行覆盖。因此,选择波束赋形的方法,通过公式推导和高频结构仿真软件(High Frequency Structure Simulator,HFSS),研究了三元微带天线线阵的电气性能随阵元夹角、阵元间距变化而变化的规律。根据仿真计算结果,提出了采用阵元夹角为60°、阵元间距为半波波长的三元微带天线线阵,提高了微带天线线阵的辐射功率,优化了波瓣宽度和指向,满足工程需求,具有一定的理论指导意义和工程实践借鉴。In the detector design of RF positioning system in an indoor environment,the antenna beam must satisfy the condition of the wide lobe and cover the whole room.Therefore,the beamforming method should be selected,and via formula derivation and HFSS(High Frequency Structure Simulator),the law of electrical performance of ternary microstrip antenna array varying with angle and spacing of the elements is explored.Based on the simulation results,a ternary microstrip antenna array with array-element angle of 60°and array-element spacing of half-wavelength is proposed.This improves the radiation power of microstrip antenna array,optimizes the lobe width and orientation,meets the engineering requirements,and thus is of certain theoretical guiding significance and reference for engineering practice.
