Abstract
The antenna is adapted to be connected to a coaxial cable and includes a dielectric carrier board and a radiating element undulating longitudinally of the carrier board. The carrier board and radiating element are disposed in a conductive channel which has side walls adjacent the side edges of the carrier board. An input transition means is provided between the center conductor of the coaxial connector and the undulating track to provide a transition from the impedance of the coaxial cable to the impedance of the radiating element of the sandwich-wire antenna. When the antenna may, or may not, be connected to a coaxial cable, the side walls extend above the carrier board for such a height that the radiating aperture, which comprises the gap between the top edges of the side walls, presents a resistive load in the plane of the radiating element.
