Abstract: A wireless electronic device (10) may include antenna structures (40U) and antenna tuning circuitry. The device (10) may include a display (14) mounted within a housing (12). A peripheral conductive member (16) may run around the edges of the display and housing. Dielectric-filled gaps (18C) may divide the peripheral conductive member (16) into individual segments (16-1, 16-2). A ground plane (G) may be formed within the housing. The ground plane (G) and the segments (16-1, 16-2) of the peripheral conductive member (16) may form antennas in upper and lower portions of the housing (12). The antenna tuning circuitry may include switchable inductor circuits (210') and variable capacitor circuits (212-1) for the upper and lower antennas. The switchable inductor circuits (210') associated with the upper antenna may be tuned to provide coverage in at least two high-band frequency ranges of interest, whereas the variable capacitor circuits (212-1) associated with the upper antenna may be tuned to provide coverage in at least two low-band frequency ranges of interest.

Abstract: An electronic device (10) has wireless communications circuitry (34) including an adjustable antenna system (40) coupled to a radio-frequency transceiver (90). The adjustable antenna system (40) may include one or more adjustable electrical components (168) that are controlled by storage and processing circuitry (28) in the electronic device (10). The adjustable electrical components (168) may include switches and components that can be adjusted between numerous different states. The adjustable electrical components (168) may be coupled between antenna system components such as transmission line elements (140), matching network elements (152), antenna elements (160) and antenna feeds. By adjusting the adjustable electrical components, the storage and processing circuitry (28) can tune the adjustable antenna system (40) to ensure that the adjustable antenna system (40) covers communications bands of interest.
