FIELD: physics.
SUBSTANCE: invention relates to UHF antennae, in particular, to phased antenna arrays (PAA) with through type spatial excitation, and is intended for use of multifunctional radar stations antenna device. PAA comprises first and second emitters arranged in rows and columns in first and second flat apertures, wherein first emitters are respectively connected to second emitters through controlled phase changer by equal electric length transmission lines, as well as first and second emitters, located on the side of first and second flat apertures, and connected with transceiver via switch, wherein angle between planes of first and second flat apertures with corresponding first and second azimuthal plane exciters is selected equal to α=180°-φ, where φ is flat aperture scanning sector width.
EFFECT: simplified design while expanding scanning sector.
