Abstract： Aiming at the problem of mutual coupling in millimeter-wave high-density arry antennas， a 2×2 microstrip patcharray antena basedon field-pair cancelation decoupling technology is proposed.By embeddingarectangularslotted resonantstructurebetweenadjacentunits，thedesignexcitesananti-phase induced electricfieldtoachieveelectromagnetic energydestructive interference，therebysignificantlyimprovingtheisolationoftheunit.Theantennaadoptsanear-coupled feedand1-to-4T-junctionnetwork，whichefectivelyexpandsthebandwidthandenancestheintegrationcapability.The simulation results show that the impedance bandwidth of the antenna is 24.82～27.42GHz ，therelative bandwidth is 10.0% and the matching is good. In the working frequency band，the gain is maintained above 7.5dBi ，the cross polarization level is significantlyduced，andtheradiationcharacteristicsareexcellent.Thisschemeprovidesanefectivedecouplingpathfor milimeter-wavehighlyintegratedarrayantennas，whichissuitableforcommunicationsystems withstrictrequirementsfor broadband and miniaturization.
