  • Patent number: 10074898
    Abstract: The present disclosure can provide a wideband antenna with a folded monopole structure that operates at GPS frequencies and high band (HB) frequencies. Accordingly, the wideband antenna can function as an integrated GPS and HB Diversity antenna for a computing device. In some embodiments, due to various constraints, the antenna can be designed to have a curved structure to fit within a corner of the computing device. The folded monopole antenna can comprise two substantially parallel conducting arms, which improves antenna performance. In some embodiments, the present disclosure can provide GPS and high band impedance matching for a signal received from the antenna in order to improve/ensure signal quality. The signal can be decoupled into a GPS signal portion and a high band signal portion for additional processing and/or information retrieval.

  • Patent number: 9929763
    Abstract: Systems and methods for addressing an inadvertent decrease in transmission energy/power due to triggering a proximity sensor by a cover disposed on a computing device. In an embodiment, a cover sensor may be incorporated into the device. The cover sensor may be used to detect the presence of a cover on the device, as well as whether the cover is in an open or closed position. The output of the cover sensor may then be used to adjust a trigger/proximity threshold of the proximity sensor to account for the presence and position of the cover on the device. In this manner the device may avoid unnecessary power backoff caused by proximity of the cover, rather than proximity of the user. This improves the over the air (OTA) performance of the device, as well as the user experience.

  • Patent number: 9867139
    Abstract: Devices and apparatuses are described. An apparatus may include radio frequency (RF) circuitry including a RF feed and a modem to transmit one or more signals via the RF feed. The apparatus may include an antenna structure including a first element and a second element.

  • Patent number: 9865920
    Abstract: An apparatus includes a first reactive component coupled between a first antenna and a second antenna in a multi-band antenna system. The apparatus further includes a first operation circuit coupled to the first reactive component. The first reactive component and the first operation circuit together form a signal path to enable signal flow between the first and the second antennas when the first and the second antennas are operating at a first frequency. The first operation circuit disables signal flow along the signal path when the first and the second antennas are operating at a second frequency.

  • Patent number: 9413058
    Abstract: Antenna structures and methods of operating the same are described. One apparatus includes a metal cover having a first corner portion, a second corner portion, and an elongated portion. The elongated portion is physically separated from the first corner portion by a first cutout in the metal cover and the elongated portion is physically separated from the second corner portion by a second cutout in the metal cover. A radio frequency (RF) circuit is coupled to a feeding element that is coupled to the elongated portion. A capacitor is coupled between the feeding element and the first corner portion near the distal end of the feeding element. The RF circuit is operable to cause the feeding element, the elongated portion, and the first corner portion to radiate electromagnetic energy as a first radiator in a first frequency range with dual resonance.

  • Patent number: 9407003
    Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a radio frequency (RF) including a surface-current dispersing circuit and an antenna structure coupled to the RF feed at a feeding point and coupled to a ground plane at a grounding point. The antenna structure comprises an even multiple of quarter-wavelength elements with a first element coupled to the feeding point and a second element coupled to the grounding point and the grounding point is located at a specified distance from the feeding point. Surface currents, generated as a result of the RF signals being applied to the RF feed at the feeding point, create a first hot spot of an even multiple of hot spots of magnetic field at the feeding point. The surface-current dispersing circuit and the ground point disperse a portion of the surface currents at the feeding point towards the grounding point to create other hot spots of the even multiple of hot spots.

  • Patent number: 9362620
    Abstract: Various embodiments provide a dynamic antenna system that adapts, by adjusting various antenna circuit parameters, to accommodate a particular circumstance or set of conditions being imposed on the computing device at a given time. For example, signal strength of the antenna system can be monitored and, upon detecting a change in the signal strength, a condition associated with the change, such as the user holding the device with two hands, can be identified based on offline testing, measurement, and pattern recognition. Accordingly, the one or more parameters of the antenna system, which can include multiple antennas and other reconfigurable components, can be adjusted to optimize the antenna efficiency for the particular condition associated with the change in signal strength.
