Abstract: A wrist-worn training computer includes one or more biosensors; a casing; a display lens positioned against the casing to form an interface between the display lens and the casing, and to enclose together with the casing an enclosed space between the casing and the display lens; a first part of an antenna of a satellite navigation receiver disposed within the enclosed space; and a gasket positioned along the interface between the display lens and the casing to seal the enclosed space. The gasket comprises electrically conductive material that forms a second part of the antenna.

Abstract: Wireless wide area network (WWAN) antenna with integrated sensor and methods of using the same. In one embodiment, an antenna subsystem and proximity sensing subsystem share a grounded antenna component/parasitic element. The parasitic element can be used to broaden the operating band of the antenna feeding component and provide an input (via a capacitance change) to a proximity sensor. The parasitic element is, in one embodiment, coupled in parallel to the proximity sensor allowing for a reduction in noise due to increased isolation between the antenna subsystem and the sensing subsystem.

Abstract: Antenna systems that make use of an integrated proximity sensor or other sensor in order to implement a closed loop antenna selection system. In one embodiment, the antenna system is implemented within an exemplary portable wireless device and includes as its primary components for implementing the closed loop antenna selection system: a proximity sensor/microcontroller unit (MCU); a switching apparatus; a baseband front end module (FEM); and a number of antenna modules. The integrated proximity sensor/MCU detects the presence (influence) of a user's hand, or other loading by any other dielectric or metal component, through measurements that take place through the antenna modules and selects the appropriate RF path for transmission and/or reception by the mobile device. Methods of using and testing the aforementioned antenna systems are also disclosed.

Abstract: Switchable multi-radiator high band antenna apparatus, and methods of tuning and utilizing the same. In one embodiment, the antenna apparatus is configured to operate in lower and upper frequency bands, for use within a handheld mobile device (e.g., cellular telephone or smartphone). In one variant, the antenna apparatus includes a metal cup, two feeding elements, and a ground element. One feeding element is used to tune the antenna in both the lower and the upper bands. The other feed element is used to tune the antenna in the upper band. A switching element is configured to change the signal routing for the feed elements. During device operation, a user's body (e.g., hand) may cover or obstruct one of the antenna elements. Responsive to a determination of reduced performance associated with covered/obstructed antenna element, the signal route may be automatically switched to the other element, thereby improving robustness of mobile device communications.
