Abstract: Electronic devices may include radio-frequency transceiver circuitry and antenna structures. The antenna structures may include a dual arm inverted-F antenna resonating element and an antenna ground. An antenna feed may be coupled between the inverted-F antenna resonating element and the antenna ground. An adjustable component such as an adjustable inductor may be coupled between the inverted-F antenna resonating element and the antenna ground in parallel with the antenna feed. The adjustable component may be operable in multiple states such as an open circuit state, a short circuit state, and a state in which the adjustable component exhibits a non-zero inductance. Antenna bandwidth can be broadened by coupling a loop antenna resonating element across the antenna feed. A portion of the antenna ground may overlap the loop antenna resonating element to further enhance antenna bandwidth.

Abstract: A test system may include test stations for testing the radio-frequency performance of wireless electronic devices. A reference test station may perform test measurements on a group of wireless electronic devices under test (DUTs) to select a reference DUT. The reference test station may gather radio-frequency measurements at a number of test frequencies from the group of DUTs. The reference test station may compute statistical data associated with the gathered measurements. The reference test station may compute weight values associated with each test frequency based on the statistical parameters. The reference test station may compute a weighted mean square error value for each DUT based on the weight values and the statistical data. The reference test station may select a DUT having a minimum weighted mean square error value to serve as the reference DUT, which may be used to calibrate test stations in the test system.

Abstract: Custom antenna structures may be used to improve antenna performance and to compensate for manufacturing variations in electronic device antennas. An electronic device antenna may include an antenna tuning element and conductive structures formed from portions of a peripheral conductive housing member and other conductive antenna structures. The antenna tuning element may be connected across a gap in the peripheral conductive housing member. The custom antenna structures may be used to couple the antenna tuning element to a fixed custom location on the peripheral conductive housing member to help satisfy design criteria and to compensate for manufacturing variations in the conductive antenna structures that could potentially lead to undesired variations in antenna performance. Custom antenna structures may include springs and custom paths on dielectric supports.

Abstract: Electronic devices may include radio-frequency transceiver circuitry and antenna structures. The antenna structures may form a dual arm inverted-F antenna and an additional antenna such as a monopole antenna sharing a common antenna ground. The antenna structures may have three ports. A first antenna port may be coupled to an inverted-F antenna resonating element at a first location and a second antenna port may be coupled to the inverted-F antenna resonating element at a second location. 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.

Abstract: A manufacturing system for assembling wireless electronic devices is provided. The manufacturing system may include test stations for testing the radio-frequency performance of components that are to be assembled within the electronic devices. A reference test station may be calibrated using calibration coupons having known radio-frequency characteristics. The calibration coupons may include transmission line structures. The reference test station may measure verification standards to establish baseline measurement data. The verification standards may include circuitry having electrical components with given impedance values. Many verification coupons may be measured to enable testing for a wide range of impedance values. Test stations in the manufacturing system may subsequently measure the verification standards to generate test measurement data. The test measurement data may be compared to the baseline measurement data to characterize the performance of the test stations to ensure consistent test measurements across the test stations.
