Number: 343/790
Name: Communications: radio wave antennas > Antennas > Active sleeve surrounds feed line
Description: Subject matter wherein an active antenna element, which may be a complete antenna or a portion of one (such as an arm of a dipole), is formed as a cylinder, prisms, or frustum of a cone or prism, or defines such a surface (such as series of circularly arranged parallel wires), is combined with a feed line which supplies radiating energy to or from this antenna element or to or from another antenna element; and which enters the cylinder at one end and extends within the cylinder at least a portion of the distance to the other end; and where the feed line is electrically coupled to this cylinder the coupling is remote from the entrance end, there being a substantial insulating space between the inner surface of the sleeve and the portion of the feed line extending within the cylinder.
