FIELD: radio engineering, communication.SUBSTANCE: radiating element of a small-size phased antenna array includes a vibrator, a matching transformer, a current-carrying reflector, a connector and dielectric elements. With that, the dielectric elements are made from radio-transparent material with dielectric permeability ?>>1, arranged and rigidly fixed between ends of the vibrator and the reflector. The device also includes a passive element and additional dielectric elements made from radio-transparent material with dielectric permeability ?>>1, arranged and rigidly fixed between ends of the passive element and the vibrator. The vibrator, the matching transformer and the passive element are made by means of a printed-circuit board manufacturing procedure in the form of sections of a metallised layer on the insulating base of the printed-circuit board of the radiator. Dielectric elements are made in the form of parts of brackets, and the reflector is made either as straight-line or U-shaped.EFFECT: enlarging the range of working frequencies.4 cl, 6 dwg |
