20160093950 | SYSTEM IN WHICH A PHASED ARRAY ANTENNA EMULATES LOWER DIRECTIVITY ANTENNAS - A system includes a phased array antenna that is used to emulate antennas that have larger solid angle coverage and lower gain compared to a single beam of the phased array antenna. This is achieved by switching between beams of the phased array antenna while receiving a wireless communication signal and summing representations of signal energy received using the different beams. The system can be used to narrow down the angular coordinates of a transmitting satellite by emulating antenna patterns that cover portions of a search space. The system can also be used to determine a channel discriminator (e.g., frequency, code, time slot) that defines a signal being transmitted. | 03-31-2016 |
20130120195 | ANTENNA SYSTEM FOR HANDHELD SATELLITE COMMUNICATION DEVICES - An antenna systems for a handheld wireless device comprises an antenna disposed proximate an oblong ground structure (e.g., oblong PCB). The antenna is suitably adapted to radiated circularly polarized waves by supporting quadrature phased first and second resonances which are associated with electrical fields oriented at right angles to each other and at an oblique angle relative to a longitudinal axis of the oblong ground structure. | 05-16-2013 |
20120280884 | CO-AXIAL QUADRIFILAR ANTENNA - Antennas that include an inner set of four helical antenna elements and a co-axially arranged outer set of four helical antenna elements. The helical winding directions of the two sets of elements may have the same handedness or opposite handedness. Certain embodiments provide for switch handedness of circularly polarized radiation of the antennas and certain embodiments provide for shifting the directivity of the antenna pattern in polar angle. Systems in which the antennas are used and methods of use are also taught. | 11-08-2012 |
20110254755 | MULTIBAND MULTIFILAR ANTENNA - Multi-band quadrifilar antennas that are suitable for satellite communication include composite elements each of which include multiple conductors operating at different frequencies connected to a bus bar. Each composite element is coupled to a signal feed and to a ground structure. | 10-20-2011 |
