The 4×4 arrayantenna obtained through theoretical research， design，simulationandoptimizationachieveshighgain.Theantennagainis19.O3dBiand thebeam widthis19.61 ° x19.97°. It canmeettherequirementsoftheradarwaterlevelgaugesystemundergraduallychangingflowandrapidlychangingflow conditions. It has good application prospects.
