FIELD: physics. ^ SUBSTANCE: device is a dipole whose radiating arm lies over a passive arm (base) and on its opposite side there is a matching circuit in form of a parallel circuit consisting of two conductors connected in series and a capacitor. The common end of the capacitor of the circuit and one of the conductors of the matching circuit are connected to the radiating arm of the dipole through a coupling capacitor, and its other ends are connected to the outer side of the passive arm of the dipole, respectively. The arms of the dipole and conductors of the matching circuit are made from plates and capacitor elements are made from pieces of coaxial cable. Corresponding ends of the arms of the dipole and the matching circuit are connected via dielectric supports. Metal grids in form of cones, on whose apexes there is an antiradar plate, can be soldered to outer sides of the radiating arm of the dipole and conductors of the matching circuit. ^ EFFECT: simple design of the matching circuit, wider transmission band with low standing-wave ratio, directivity and noise immunity. ^ 2 cl, 4 dwg |
