Abstract: An electronic device may be provided with wireless circuitry. Control circuitry may be used to adjust transmit power levels for wireless signals, may be used to tune antennas, and may be used to adjust other settings for the wireless circuitry. The electronic device may have a coupler interposed between an antenna and wireless transceiver circuitry. The coupler and a receiver within the transceiver circuitry may be used to make measurements on tapped antenna signals such as transmitted signals and signals reflected from the antenna. By analyzing the tapped antenna signals, S-parameter phase and magnitude information may be gathered that provides insight into whether the electronic device is operating properly and whether an external object is adjacent to the antenna. If an external object is present, the electronic device may limit wireless transmit power and may adjust tunable components in the antenna to compensate for detuning from the external object.

Abstract: A test station may include a test host, testing devices, and a test enclosure. A device under test (DUT) having a near-field communications (NFC) antenna may be placed in the test enclosure during production testing. The testing devices may have test antennas that may convey NFC test signals to the DUT in the test enclosure. Distances between test antennas and the DUT may be monitored by measuring path loss from the test antennas throughout testing. The testing station may also include a test unit and an RF test antenna. The test unit may use the RF test antenna to convey RF test signals to the DUT in the test enclosure. The DUT is marked as a passing DUT if gathered test data is satisfactory for each testing device in the test station and distance measurements between the test antennas and the DUT throughout testing are consistent with calibration measurements.

Antenna structures that are located between respective upper and lower antenna windows on the upper and lower surfaces may be based on a pair of antennas that are coupled to switching circuitry that can select which antenna to switch into use or may be based on an antenna having a position that may be adjusted relative to the upper and lower antenna windows using a mechanical coupling to the lid or using a positioner. A sensor such as a lid position sensor may monitor how the lid is positioned relative to the base unit. Information from the lid position sensor may be used in adjusting the antenna structures to optimize performance.

A third antenna port may be coupled to the additional antenna. An adjustable component may be coupled to the first antenna port to tune the inverted-F antenna. The inverted-F antenna may be near-field coupled to the additional antenna so that the inverted-F antenna may serve as a tunable parasitic antenna resonating element that tunes the additional antenna.
