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: Abstract of the Disclosure Electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. A parallel 5 fed loop antenna may be formed from portions of a conductive bezel and a ground plane. The antenna may operate in multiple communications bands. The bezel may surround a peripheral portion of a display that is mounted to the front of an electronic device. The bezel may 10 contain a gap. Antenna feed terminals for the antenna may be located on opposing sides of the gap. A variable capacitor may bridge the gap. An inductive element may bridge the gap and the antenna feed terminals. A switchable inductor may be coupled in parallel with the 15 inductive element. Tunable matching circuitry may be coupled between one of the antenna feed terminals and a conductor in a coaxial cable connecting the transceiver circuitry to the antenna.
