Abstract
The application provides a kind of double-layer substrate integrated gap waveguide ultra-wideband dual-polarized array antenna, it relates to microwave millimeter wave antenna technical field, from bottom to top, feed layer, radiation layer and impedance matching layer are sequentially stacked and arranged, feed layer is the feed network formed by double-layer substrate integrated gap waveguide;Radiation layer includes a plurality of interval arrangement magnetic electric dipole radiating unit, each magnetic electric dipole radiating unit on radiation layer is connected to feed layer by corresponding feed structure, to receive the X direction polarized wave or Y direction polarized wave transmitted by feed network;Impedance matching layer is used to radiate the radiation energy generated by the X direction polarized wave or Y direction polarized wave received by radiation layer to air.This application is fed by the feed network formed by double-layer substrate integrated gap waveguide, so that the array antenna is fed in a wider frequency band, meets the demand of realizing double linear polarization radiation of array antenna in 19-28.5GHz frequency band.
