Abstract
An antenna minimizes radiation from the outer conductor () of a coaxial cable () that is coupled to the antenna by providing a balancing tab () that lies near the connection () of the cable outer conductor () to the antenna. One antenna includes a Yagi structure () constructed of a plate of metal that forms a long boom () and a plurality of directors () extending laterally across the boom, with an electrical coupling loop mounted at a rear region of the Yagi structure. The coupling loop includes a folded dipole in the form of a metal coupling plate that forms a loop () with a gap (), the loop having a laterally elongated front loop end (). The Yagi structure is formed with a balancing tab () that lies forward of the loop, that has a lateral length (D) less than half that of one of the directors, and that extends from only one side () of the boom which is the side to which the outer coax conductor () is connected to the loop. The metal coupling plate lies facewise adjacent to a face () of the Yagi plate, with a dielectric spacer () between them.
