  • Patent number: 10199729
    Abstract: An antenna includes a stack of cylindrical lenses combined with feed elements to provide multi-beam coverage for a given wireless communication sector. Each cylindrical lens disc has approximately the same height as the feed elements being used with the lens. To overcome the problem of interference from cables and opposing feeds, feed elements are placed around the lens. The cylindrical lenses are stacked such that a small gap exists between each pair of adjacent cylindrical lenses, allowing for cable lines to pass through between the pair of the cylindrical lenses, and thus removing interference for 360 degree coverage. Cable lines are arranged such that they only traverse the portion of the circumferential surfaces of the cylindrical lenses that do not interfere with the field of view of the RF signals generated by the corresponding feed elements.

  • Patent number: 10181655
    Abstract: A horizontally polarized antenna array allows for the efficient distribution of RF energy into a communications environment through selectable antenna elements and redirectors that create a particular radiation pattern such as a substantially omnidirectional radiation pattern. In conjunction with a vertically polarized array, a particular high-gain wireless environment may be created such that one environment does not interfere with other nearby wireless environments and avoids interference created by those other environments. Lower gain patterns may also be created by using particular configurations of a horizontal and/or vertical antenna array. In a preferred embodiment, the antenna systems disclosed herein are utilized in a multiple-input, multiple-output (MIMO) wireless environment.

  • Patent number: 10171139
    Abstract: A communication system utilizing reconfigurable antenna systems is described where beam steering and null forming techniques are incorporated to limit the region or volume available for communication with client devices. The communication system described restricts communication to defined or desired area and degrades signal strength coverage outside of a prescribed region. An algorithm is used to control the antenna system to monitor and control antenna system performance across the service area. This antenna system technique is applicable for use in communication systems such as a Local Area Network (LAN), cellular communication network, and Machine to Machine (M2M).

  • Patent number: 10158182
    Abstract: A first waveguide guides a first radio wave whose electric field is vibrated in a first direction along a second direction. A second waveguide guides the first radio wave along the second direction and is cascade connected to the first waveguide. An input and output end multiplexes the first radio waves from the first and second waveguides and outputs the multiplexed radio wave, and outputs the first radio wave branched off from a radio wave from outside to the first and second waveguides. A first waveguide shift portion is shifted from the first waveguide in the first direction. A second waveguide shift portion is shifted from the second waveguide in the first direction. The vibration directions of electric fields of radio waves passing through the end parts of the first and second waveguide shift portions are rotated by 90° about a third direction.
