Abstract: An electronic device may be provided with wireless circuitry that is tested in a test system. The test system may include test probes. Circuitry under test may wirelessly transmit test signals. The test probes may receive the test signals at multiple locations. Circuitry may measure direct current (DC) voltages generated by the test probes and may convert the voltages to electric field magnitudes. A test host may process the electric field magnitudes to determine whether the circuitry under test exhibits a satisfactory radiation pattern. The test probes may include dielectric substrates and one or more dipole elements coupled to respective diodes. The dipole elements may include indium tin oxide (ITO) and may include first and second sets of orthogonal dipole elements. Transmission lines coupled to the dipole elements may include ITO and may form low pass filters that convert rectified voltages produced by the diodes into the DC voltages.

Abstract: An electronic device such as a laptop computer may have an upper housing and a lower housing. The lower housing may have a clutch barrel coupled to the upper housing by a hinge. The upper housing may be rotatable relative to the lower housing between an open position and a closed position. The upper housing may have a curved metal surface facing the clutch barrel. The device may have an antenna with a radiating arm on a curved interior surface of a substrate in the clutch barrel. The radiating arm may extend parallel to the curved metal surface. The radiating arm may remain separated from the curved metal surface across its lateral area as the upper housing is rotated from the open position to the closed position. This may ensure that the antenna is provided with a uniform capacitive load from the upper housing at all upper housing positions.

Abstract: An electronic device may have an upper housing and a lower housing separated by a slot. An antenna module may be mounted in the lower housing and may include a cavity. An antenna element may be disposed within the cavity. Grounded traces may be patterned onto walls of the module and may be coupled to conductive walls of the lower housing by conductive gaskets. The antenna element may have a high band arm displaced farther into the cavity than a low band arm by a shim. The antenna module may have an acoustic port aligned with a speaker port. The acoustic port may allow sound waves from a speaker to pass into the cavity from the speaker port. The cavity may be configured to optimize an audio response of the speaker while concurrently optimizing radio-frequency performance of the antenna element.

Abstract: An electronic device may have an upper housing and a lower housing separated by a slow. A substrate may be mounted in the lower housing and may have an inner surface facing an interior of the lower housing and an outer surface facing the slot. Ventilation port openings may extend from the outer surface to the inner surface. Ribs in the substrate may separate the ventilation port openings. The ribs may include notches at the inner surface. An antenna may include conductive traces within multiple ventilation port openings and extending through the notches. The conductive traces may be offset from the outer surface. The outer surface of the substrate may be free from conductive material from the antenna. This may serve to maximize antenna efficiency while protecting the antenna from external forces and debris or other contaminants that pass through the slot during use of the electronic device over time.
