US Patent:

57343500, Mar 31, 1998

Filed:

Apr 8, 1996

Appl. No.:

8/629230

Inventors:

Douglas Robert Deming - Boulder CO
Dax Craig - Boulder CO
Robert Eugene Munson - Boulder CO
Joseph Theofil Negler - Boulder CO

Assignee:

Xertex Technologies, Inc. - Boulder CO

International Classification:

H01Q 138

US Classification:

343700MS

Abstract:

A Radio Frequency (RF) microstrip antenna employs a planar or curved radiator element that is mounted or supported in spaced relation to a planar or curved ground plane element. A RF feed is attached near one edge of the radiator element for receiving and/or transmitting RF signals in a lobe that is substantially perpendicular to the ground plane element. The radiator element and the ground plane element are maintained in a converging or tilted physical relationship. When a coaxial cable is employed as the antenna feed, the cable's outer insulation is secured to the ground plane element, the cable's center conductor extends away from the ground plane element to provide a signal feed to the radiator element and to provide physical support for one edge of the radiator element, and two insulator posts extend away from the ground plane element to provide support for the opposite edge of the radiator element.

International Classification:

H01Q 138

US Classification:

343700MS

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.

US Classification:

Abstract:

A Radio Frequency (RF) microstrip antenna employs a planar or curved radiator element that is mounted or supported in spaced relation to a planar or curved ground plane element A RF feed is attached near one edge of the radiator element for receiving and/or transmitting RF signals; in a lobe that is substantially perpendicular to the ground plane element. The radiator element and the ground plane element are maintained in a converging inclined or tilted physical relationship. When a coaxial cable is employed as the antenna feed, the cable's outer insulation is secured to the ground plane element, the cable's center conductor extends away from the ground plane element to provide a signal feed to the radiator element and to provide physical support for one edge of the radiator element, and two insulator posts extend away from the ground plane element to provide support for the opposite edge of the radiator element. A two-piece, snap-together, radome is provided, wherein a bottom half nonmovably supports the feed line and ground plane member and adjustably supports the inclined radiating element, wherein a top half snap-fits to the bottom half and wherein the top half includes internal extenting tabs that engage edge portions of the ground plane member.
