Patent number: 6911939Abstract: An antenna system can generate RF radiation fields having dual simultaneous polarization states and having substantially rotationally symmetric radiation patterns. The antenna system generates RF radiation patterns where the beamwidths of respective RF fields for respective radiating elements are substantially equal and are relatively large despite the compact, physical size of the antenna system. The antenna system can include one or more patch radiators and a non-resonant patch separated from each other by an air dielectric and by relatively small spacer elements. The patch radiators and non-resonant patch can have predefined shapes for increasing polarization discrimination. The lower patch radiators can be mounted to a printed circuit board that can include an RF feed network and a ground plane which defines a plurality of symmetrically, shaped slots. The slots within the ground plane of the printed circuit board can be excited by stubs that are part of the feed network of the printed circuit board.Type: GrantFiled: August 20, 2002Date of Patent: June 28, 2005Assignee: EMS Technologies, Inc.Inventors: James C.

Patent number: 6897809Abstract: A compact antenna system can generate RF radiation fields having increased beamwidths and bandwidths. The antenna system can include one or more patch radiators. The lower patch radiators can be mounted to a printed circuit board that can include a ground plane which defines a plurality of slots. The slots within the ground plane of the printed circuit board can be excited by stubs that are part of the feed network of the printed circuit board. The slots, in turn, can establish RF radiation in a cavity which is disposed adjacent to the ground plane of the printed circuit board and a ground plane of the antenna system.Type: GrantFiled: March 4, 2002Date of Patent: May 24, 2005Assignee: EMS Technologies, Inc.Inventors: James C. Carson, James K. Tillery, Sara Phillips

Patent number: 6682354Abstract: Using a method and apparatus for connecting an electrical cable to a circuit board. The connector is largely semi-circular in shape and generally comprises four prongs for attaching the connector to the edge of a circuit board. The connector is particularly useful for attaching a coaxial cable to a circuit board where the coaxial cable is not very flexible. The coaxial cable can be easily placed onto the connector. Once the coaxial cable is placed on the connector, the outer conductor can be attached to the connector and the inner conductor can be attached to the circuit board.Type: GrantFiled: February 15, 2002Date of Patent: January 27, 2004Assignee: EMS Technologies, Inc.Inventors: James C.

Patent number: 6067053Abstract: A planar array antenna having radiating elements characterized by dual simultaneous polarization states and having substantially rotationally symmetric radiation patterns. A distribution network, which is connected to each dual polarized radiator, communicates the electromagnetic signals from and to each radiating element. A ground plane is positioned generally parallel to and spaced apart from the radiating elements by a predetermined distance. The conductive surface of the ground plane operates to image the radiating elements over a wide coverage area, thereby enabling a radiation pattern within an azimuth plane of the antenna to be independent of any quantity of radiating elements. Side walls, placed on each side of the array of radiators, can operate in tandem with the ground plane, to reduce the half-power beamwidth in the azimuth plane for a selected radiator design.Type: GrantFiled: October 18, 1996Date of Patent: May 23, 2000Assignee: EMS Technologies, Inc.Inventors: Donald L. Runyon, James E. Thompson, Jr., James C. Carson
