摘要 基于北斗的地下管网及窖井井盖监控是实施城市安全和智慧城市的重要手段,目前存在着监测系统中天线受井盖影响大、安装困难、接收性能差等问题.本文针对上述问题设计了一种应用于北斗B1和GPSL1频段的方形圆极化微带天线,克服目前窖井井盖特殊环境北斗天线安装困难、频带窄易受干扰等缺点.采用ANSOFTHFSS软件进行天线性能仿真,仿真结果表明:设计的井盖北斗天线有效中心频率为1568MHz,电压驻波比小于1.5,波束宽度L1:1575.42±1.023MHz,B1:1561.42±2.048MHz,符合地下管网及窖井井盖监测的实际应用要求. Based on the Beidou manhole covers and underground pipe network the monitoring wells is an important means of the implementation of urban security and the smart city, In monitoring system, there are some problems of antenne affected by covers largely, installation difficulties and poor reception performance. Aiming at these problems, this paper designed a circularly polarized microstrip antenna ap- plied to Beidou B1 and GPSL1 band, to overcome the current manhole wells covers special environment Beidou antenna installation difficulties, narrow-band susceptible to interference and other shortcomings. The ANSOFT HFSS simulation indicates that the design of the Beidou covers antenna effective center frequency of 1 568 MHz, VSWR less than 1. 5, the beam width LI: 1575. 42 ± 1. 023 MHz BI: 1 561. 42±2. 048 MHz, in line with the underground pipe network and actual application requirements manhole covers monitoring wells.
