FIELD: multi-unit band microwave antennas. ^ SUBSTANCE: regularly arranged perpendicularly to the plane of the common parasitic reflector are symmetrical band dipoles, whose arms are powered in antiphase by symmetrical band lines provided with symmetrically-matching devices. The symmetrical band dipoles are made in the form of built-up three-layer constructions. The arms of the dipoles represent two extreme similar and one central ones, with opposite orientation in the plane of the array with respect to the extreme ones, bands, passing to the band sections located over the common parasitic reflector and connected at an angle of 90 deg. To the longitudinal axis of the dipole arms to the end faces of the mentioned bands. The band section connected to the arm of the dipole, being the central band, has a linear bevel with a narrowing of the width towards the arm by one third at a distance making up a quarter of the medium length of the wave of the working band, and an adjusting recess in the point of connection of the band section to the end face of the central band within the half-width of the band. ^ EFFECT: improved mass and dimensional characteristics, adaptability to manufacture. ^ 2 cl, 8 dwg |
