摘要
Abstract
With the development needs of diversified water resources and environmental perceptions such as smart water conservancy and smart water,the requirements for monitoring factors such as water levels and flow rates in rivers and pipelines are becoming increasingly high.How to increase antenna gain and reduce sidelobe is the main design goal to improve the ranging range and measurement accuracy of radar water level gauge.In this paper,a 24 GHz radar water level gauge 4×4 microstrip antenna array is designed by using the transmission line theoretical model research method,and an innovative idea of an ideal power splitter based on the excitation port is proposed,which provides an objective and accurate comparison reference object for the performance evaluation of actual power splitter.The 4×4 array antenna obtained through theoretical research,design,simulation and optimization achieves high gain.The antenna gain is 19.03 dBi and the beam width is 19.61°×19.97°.It can meet the requirements of the radar water level gauge system under gradually changing flow and rapidly changing flow conditions.It has good application prospects.关键词
