<p>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 (15), a two-section shorting element that is defined by two generally parallel fold lines (16, 17), a radiating element (14), and an arm (18) 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 (30) is aligned with a gap (115) that is formed between the two sections of the shorting element. The cable's outer metal sheath (32) is connected to a metal tab (48), and the metal tab is secured to a surface of the ground plane element. The cable's center conductor (31) is secured to a surface of the radiating element. A radome and its mounting tab complete the antenna assembly.</p> |
