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.

Abstract: Antenna structures and methods of operating the same of an electronic device are described. One wearable electronic device includes a housing of conductive material and an antenna structure disposed on or within a band that is used to affix to a user. The antenna structure includes a first connector, a second connector, and a first antenna element. The first and second connectors extend out from sides of the band and electrically couple to a RF feed and a ground point when the first and second connectors are physically coupled to the housing. The RF circuitry is operable to cause a first current flow on at least the first antenna element via the first connector to radiate electromagnetic energy in a first frequency range.

Abstract: Dynamic tuning of antennas towards a receive channel carrier frequency, a transmit channel carrier frequency, or between the receive channel and transmit channel carrier frequencies in frequency division duplex (FDD) communications systems is disclosed. A user device, such as a mobile communications device may be configured to dynamically tune its antenna based at least in part on the amount of data to transmit, data to receive, a receive channel quality, and/or a transmit channel quality. The antenna may be tuned to one of the transmit or receive channels or a frequency between the transmit and receive channels based at least in part on which channel, if any, may benefit from greater antenna efficiency.

Abstract: A user device selects a communication module from a plurality of communication modules of the user device to communicate first data to a first device in a first configuration, selects a first antenna from a plurality of antennas of the user device to communicate the first data in the first configuration, and couples the communication module to the first antenna in the first configuration. The user device additionally selects the communication module to communicate second data to a second device in a second configuration, selects the first antenna and a second antenna from the plurality of antennas to communicate the second data in the second configuration, and couples the communication module to the first antenna and the second antenna in the second configuration.

Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a single radio frequency (RF) feed and a folded monopole element coupled to the single RF feed. The folded monopole element is an integrated WAN/GNSS antenna that receives electromagnetic energy in a first frequency band and receives electromagnetic energy in a second frequency band. The first frequency band is a wireless area network (WAN) frequency band and the second frequency band is a global navigation satellite system (GNSS) frequency band. The apparatus further includes an impedance matching circuit coupled to the single RF feed. The impedance matching circuit includes a diplexer to extract out GNSS frequency signals received by the folded monopole element from WAN signals received by the folded monopole element.

Abstract: Data about concentration of one or more types of molecules present within a human body are determined noninvasively using radio frequency (RF) signals. Signals at several different frequencies at very low power levels are emitted using an antenna mounted to a wearable device. Operating values, such as changes to the impedance of the antenna resulting from interaction between the RF signals and the user, are associated with the concentration of one or more types of molecules within the user. These changes in impedance may be relatively small. Circuitry in the device determines internal impedance of the circuitry, compensating for internal impedances and improving overall accuracy of the measured impedance resulting from interaction with the user.

Abstract: Data about concentration of one or more types of molecules present within a human body are determined noninvasively using radio frequency signals. Signals at several different frequencies at very low power levels are emitted using an antenna mounted to a wearable device. The antenna includes nested elements of different sizes. Operating values, such as changes to the impedance of the antenna, are associated with the concentration of one or more types molecules within the user. Concentrations at different depths may be measured by using different sets of the nested elements at different times. Operating values at those times are measured and used to determine information indicative of concentration of the molecules. During use, a long axis of the antenna may be aligned with a long axis of a user's arm.
