A microstrip antenna includes a ground plane element and a radiating element. An elongated trough is formed generally in the middle of the radiating element so as to divide the radiating element into two generally equally-sized portions, and in a manner to extend outward from a bottom surface of the radiating element. The trough includes a first side edge, a second side edge, and a bottom surface. A first radiating portion extends from the first side edge, and a second radiating portion extends from the second side edge. The trough provides an elongated microstrip-size element at the bottom surface of the trough. A relatively thin dielectric layer is provided between the bottom surface of the trough and a corresponding portion of the ground plane element, thereby providing that a microstrip transmission line is formed by the bottom surface of the trough, the thin dielectric layer, and the corresponding portion of the ground plane element. A first feed conductor is connected to the ground plane element, and a second feed conductor is connected to the bottom of the trough.

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.
