ABSTRACT:
An antenna having efficient operation over a wide bandwidth, a low standing wave ratio and constant radiation characteristics over a wide bandwidth includes in one embodiment a set of four linear elements of substantially the same length. Each linear element has a base end and a distal end. The base ends are coupled together and adapted to be connected to a transmission line which is adapted to be connected to a communication device. The linear elements are disposed about the median axis of the antenna and diverge outward from their base ends relative to the median axis. Each linear element has continuous tapered resistive loading along its length. In another version of the invention each linear element is made up of a plurality of conducting elements interconnected by discrete resistive devices.
