Patent number: 10320094Abstract: A horizontally polarized antenna may be mounted or operated with a vertical axis of the antenna being substantially perpendicular to a plane defined by the surface of the earth, and still emanate an electric field that is parallel to the surface of the earth. Use of horizontal polarization may improve communications reliability by reducing interference from predominantly vertically polarized signals in overlapping and adjacent frequency bands. Also, a vertically polarized antenna may be mounted or operated with a vertical axis of the antenna being substantially vertical to a plane defined by the surface of the earth, and still emanate an electric field that is vertical to the surface of the earth. A horizontally polarized antenna and a vertically polarized antenna mounted with their vertical axes collinearly aligned, but both antennae physically separated, provide a compact dual polarized unit emanating vertical and horizontal polarized electric fields.Type: GrantFiled: December 30, 2016Date of Patent: June 11, 2019Assignee: LHC2 INCInventor: Royden M. Honda

Patent number: 9425515Abstract: Horizontally polarized and dual polarized antennas are described herein. In some examples, a horizontally polarized and dual polarized antenna may be mounted or operated with the physical vertical axis of the antenna being substantially perpendicular to a plane defined by the surface of the earth, and emanate an electric field that is parallel to the surface of the earth. The antenna may have a multi-slot aperture that reduces a variation in the far field omni-directional pattern. The antenna may have various cross-sectional configurations, and may have a radome at least partially surrounding the antenna and a supporting structure.Type: GrantFiled: September 4, 2015Date of Patent: August 23, 2016Assignee: LHC2 INCInventors: Royden M. Honda, Robert J. Conley, Jon Thorpe

Patent number: 9258051Abstract: An Adaptive Polarization Array (APA) Algorithm is described for analyzing a wireless signal transmitted by an entity to determine a received polarization of the received wireless signal at a non-coherent receiver. The APA Algorithm determines a transmit polarization state for a transmitter to transmit signals to the entity based in part on the determined received polarization. The transmitter is an arbitrary-polarized transmitter configured to transmit signals at any polarization.Type: GrantFiled: June 11, 2013Date of Patent: February 9, 2016Assignee: LHC2 INCInventors: Timothy Leonard Hillstrom, Robert J. Conley

Patent number: 8954023Abstract: An Adaptive Polarization Array (APA) Algorithm is described for adjusting the polarization orientation of antennas, such as Dual-polarized array antennas. The APA Algorithm searches to find a polarization state that maximizes a signal quality of a received signal in the presence of interfering signals and noise. The search facilitates adjustment of a polarization state of, for example, receive antennas to maximize a signal quality metric. A proxy metric having no local maxima other than the global maximum is used to search the polarization search domain to find a best polarization state.Type: GrantFiled: June 21, 2012Date of Patent: February 10, 2015Assignee: LHC2 IncInventors: Timothy Leonard Hillstrom, Robert J.

Patent number: 8570239Abstract: Antennas that can transceive signals in a horizontally-polarized, omni-directional manner are described. In an example embodiment, an antenna comprises a spiraling surface having a spiral cross-section, the surface forming an internal cavity, an internal channel to the external surface, and an internal wall common to the cavity and the channel. Further, an example embodiment comprises a longitudinal opening allowing access to the cavity and the channel by a transmission feed line. Alternate embodiments comprise various cross-sectional configurations, and may also comprise a radome at least partially surrounding the antenna spiraling surface and supporting structure.Type: GrantFiled: October 8, 2009Date of Patent: October 29, 2013Assignee: LHC2 Inc.Inventors: Royden M.

Patent number: 8203500Abstract: Antennas that can transceive signals in an elliptically-polarized, omni-directional manner are described. In an example embodiment, an antenna comprises two elements proximally located to each other at a predetermined distance, such that two orthogonally-polarized omni-directional electromagnetic waves are tranceived. In a further example, the two elements are supported by an internal printed circuit, the printed circuit including conductors configured to supply a feed to the elements, which may be contained within a radome. Alternate embodiments comprise a plurality of elements of varying lengths.Type: GrantFiled: January 22, 2010Date of Patent: June 19, 2012Assignee: LHC2 IncInventors: Royden M. Honda, Robert J. Conley
