TRANSCEIVER ANTENNA OF PHASED ARRAY Russian patent published in 2002 - IPC

FIELD: antenna engineering. SUBSTANCE: transceiver antenna has dielectric radiators whose lengths are chosen with a view of ensuring desired mechanical strength and stiffness of antenna assembly curtain, and phase shifter incorporating magnetizing winding inside magnetic core and cylindrical ferrite rod mounted inside magnetizing winding. Matching dielectric disks are fitted between ends of cylindrical ferrite rod and dielectric radiators; cylindrical ferrite rod, matching disks, and dielectric radiators are similar in diameter and are inserted in common section of metallized round waveguide. Each dielectric radiator bears on its surface tapered groove closed over circumference with metal coating deposited on its surface; loose ends of dielectric radiators are of conical or cylindrical shape. Two diametrically opposite longitudinal slits are made in walls of common section of metallized round waveguide abutting against cylindrical ferrite rod. Magnetic core is made in the form of two U-shaped clamps each incorporating longitudinal plate mounted above respective slit and shoes resting on surface of common metallized-waveguide section; bearing surface of shoes follows shape of common section circumference of metallized round waveguide and has slot in its top part along symmetry axis; bearing surfaces of shoes are ground to high degree of precision and tightly fitted to common section surface of metallized round waveguide. EFFECT: reduced loss of microwave energy. 9 cl, 4 dwg
