  • Patent number: 9419332
    Abstract: The present invention relates to a series fed collinear antenna which includes cone-shaped radiating elements energized via a series fed common transmission line. Phasing stubs are provided between selected radiating elements and are oriented such that the phasing stub improves gain and reliability by affecting the signal to produce a beneficial elevational coordinate signal pattern. A ground plane may be provided proximate the lower end of the antenna structure to further enhance the radiated signal. The ground plane may be formed in the shape of a dome having an apex vertically disposed above a rim.

  • Patent number: 9407001
    Abstract: The present invention relates to an antenna assembly for transmitting and receiving electromagnetic waves. More particularly, this invention relates to a wideband and multiband omnidirectional antenna assembly for sending and receiving radio waves. Specifically, this invention relates to a radiative antenna element formed by way of a single-fed spiraled sheet of conductive material. The conductive material is interlaced with a dielectric material to form the radiative element. The radiative element includes a height of substantially less than ¼ of the characteristic wavelength of the lowest operating frequency.

  • Patent number: 9356340
    Abstract: The present invention relates to a series fed collinear antenna which includes cone-shaped radiating elements energized via a series fed common transmission line. Phasing stubs are provided between selected radiating elements and are oriented such that the phasing stub improves gain and reliability by affecting the signal to produce a beneficial elevational coordinate signal pattern. The radiating elements may be cones. Each cone has an associated base diameter. The base diameter may be uniform, resulting in similarly sized cones, or a cone may have a distinct base diameter resulting in differently sized cone elements.

  • Patent number: 9337793
    Abstract: A system and method for an audio system with two or more speakers, drivers, sources and the like is presented. An audio system includes a first speaker that reproduces sounds in a first frequency range and a second speaker that reproduces sounds in second frequency range. A crossover frequency is formed between the first frequency range and the second frequency range. The first speaker and the second speaker are physically separated by more than one wavelength of the crossover frequency and the first speaker is arranged horizontal with respect to the second speaker.

  • Patent number: 8878744
    Abstract: An antenna assembly having a characteristic frequency band includes an antenna feed, operatively connected to one of a radio frequency (RF) transmitter, an RF receiver, and an RF transceiver system, and a ground component. A first set of conductive elements, including either or both of linear, bent linear, and curvilinear elements, is operatively connected to the antenna feed. A second set of conductive elements, including either or both of linear, bent linear, and curvilinear elements, is operatively connected to the ground component. Each of the first set of linear conductive elements and the second set of linear conductive elements are configured as to provide substantially equal sensitivity within the characteristic frequency band across all elevation and azimuth angles.

  • Patent number: 8816934
    Abstract: An antenna assembly is provided, including a first radiative element. The first radiative element is oriented such that a first end of the radiative element is operatively connected to an antenna feed and at least a portion of the radiative element includes a first conical, helical coil. The first conical, helical coil reaches a maximum diameter at a point farthest from the antenna feed. A counterpoise structure includes one of an electrically conductive ground structure operatively connected to a ground associated with the antenna feed and a second radiative element operatively connected to the antenna feed and the first radiative element at the antenna feed.

  • Patent number: 8717250
    Abstract: Antenna assemblies are provided for receiving and transmitting radio frequency signals over an enhanced frequency band. An assembly includes an electrically conductive ground reference and a radiative element formed from an electrically conductive material and comprising an apex. The radiative element is electrically connected to an antenna feed at the apex and configured such that the radiative element lacks two-fold rotational symmetry around a first axis coinciding with the antenna feed. The radiative element extends such that a distance between the radiative element and the electrically conductive ground reference increases as a radial distance from the first axis along the radiative element increases.
