摘要： An antenna minimizes radiation from the outer conductor (44) of a coaxial cable (40) that is coupled to the antenna by providing a balancing tab (90) that lies near the connection (72) of the cable outer conductor (44) to the antenna. One antenna includes a Yagi structure (12) constructed of a plate of metal that forms a long boom (20) and a plurality of directors (28) 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 (54) with a gap (70), the loop having a laterally elongated front loop end (60). The Yagi structure is formed with a balancing tab (90) 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 (22) of the boom which is the side to which the outer coax conductor (44) is connected to the loop. The metal coupling plate lies facewise adjacent to a face (24) of the Yagi plate, with a dielectric spacer (76) between them.

摘要： In a wireless IC tag, metallic antennas are deposited as thin films on the front and back surfaces of a spacer, made of a heat-resistant glass epoxy material having a desired dielectric constant, to form a first antenna and a second antenna. An IC chip is mounted in the center of the first antenna. The second antenna functions as an auxiliary antenna for resonating to a desired frequency of a transmission radio wave of the first antenna to strengthen the intensity of the radio wave. Accordingly, even when the IC tag is mounted to a cable or the like, the tag can be mounted in the interior of the enclosure of the cable and thus the radio wave intensity of the first antenna can be prevented from being weakened by a metallic member in the cable.

摘要： A shaped antenna element that radically reduces the physical size needed for resonance without the use of lossy loading elements, while at the same time allowing direct connection to a coaxial feeder. The element is composed of at least two sub-elements in close proximity to each other, coupled electrically to each other such that the radiation resistance of the composite element is increased substantially. The composite element can be used either as an antenna or part of an antenna that consists of multiple such elements in order to provide increased directivity.
