Abstract: In a directional antenna, particularly for television receivers, in which a loop antenna element consists of at least three arcuate conductive members, output terminals are connected between two of the adjacent ends of the conductive members and impedance means are connected between the other adjacent ends of the conductive members so as to determine the distribution of a current flowing to the antenna element.

Abstract: A directional antenna comprises a pair of semi-circular antenna members arranged to form a loop, each of the antenna members includes arcuate upper and lower wire-like conductive elements which are at a small distance from each other, at the middle of the respective antenna member, and at a relatively large distance from each other at the ends of the antenna member, and interconnecting elements are connected to the upper and lower conductive elements at the ends of each antenna member, and are preferably integral wire-like extensions of the upper and lower elements. Output terminals are connected to one of the antenna members at the narrow portion thereof, and an impedance acting as a dummy load is connected to the narrow portion of the other antenna member. The interconnecting elements at the adjacent ends of the antenna members being held in opposing spaced relation to form impedances therebetween for determining the distribution of current flow in the directional antenna.

Abstract: In a directional loop antenna, particularly for television receivers, in which a pair of arcuate conductive members are mounted in opposed relation with their concave sides facing each other to define a loop, a dummy load is connected between two of the adjacent ends of the conductive members and output terminals are connected to the opposite adjacent ends, the conductive members are formed with relatively narrow end portions and relatively wide middle portions to increase the frequency band width and gain of the antenna.
