    摘要: A system includes an antenna, an impedance measurement circuit, an impedance tuning circuit, and a controller. The impedance measurement circuit can include a test current source that conveys a test current through the antenna, and a voltage sensor that measure a voltage across the antenna while the test current is conveyed through the antenna. The impedance tuning circuit can be coupled to the antenna leads and can include one or more reactive elements that can be selectively coupled to the antenna, or otherwise adjusted, to effect adjustment of the impedance connected to the antenna. The controller can: (i) use the impedance measurement circuit to obtain a measurement indicative of an impedance of the antenna; (ii) determine an adjustment to the impedance tuning circuit based on the obtained measurement; and (iii) cause the impedance tuning circuit to make the determined adjustment.

    摘要: A wearable electronic device is described. The wearable electronic device includes two communications antennae. A first antenna of the two is a current-carrying antenna electrically and physically connected to a printed circuit board of the wearable electronic device and housed in a first portion of a housing that is configured for mounting on a person's skin. A second antenna of the two is a scatterer antenna physically connected to an interior surface of a second portion of the housing and configured to overlap a portion of the current-carrying antenna. The second portion of the housing faces away from the person's skin when the wearable device is mounted on the person's skin. Current from the current-carrying antenna is induced in the scatterer antenna to enable communications between the wearable electronic device and one or more other electronic devices.
