Abstract
An antenna is formed from a single sheet of generally planar metal that is cut to provide four geometric antenna shapes that comprise a ground plane element, a two-section shorting element that is defined by two generally parallel fold lines, a radiating element, and an arm that has one end fixed to a generally central portion of the radiating element and has a free end that extends toward a fold line. Folding the metal sheet on the two fold lines positions the radiating element above the ground plane element. A transmit/receive coaxial cable is aligned with a gap that is formed between the two sections of the shorting element. The cable's outer metal sheath is connected to a metal tab, and the metal tab is secured to a surface of the ground plane element. The cable's center conductor is secured to a surface of the radiating element. A radome and its mounting tab complete the antenna assembly.
