Abstract:Thenovelhighdensityintegrateddesignmethodoftheincorporatephasedarrayantennacombiningwith

structureandfunctionwasproposed.Theincorporatephasedarrayantenna,includingantennaarray,tiletransmittingand

receving(TR)module,terminalcontroldevice,andfeedingnetwork,wasrealizedbyusinglowtemperatureco-fired

ceramics(LTCC)technique.Andthen,thedesignsofsystemstructure,collectivitycapabilityevaluation,conformal

load-bearingradome,antennaarray,andheatdesignweresimulatedandanalyzedbyusingsofterwaresuchasANSYSand

soon.Finally,theprototypewasmanufacturedandmeasured.TheresultsshowthatEIRPof23.6dBwandnoiseof3.57dB

oftheantennaareobtained.Allthemeasureddatamatchwellwiththesimulation.
