Abstract: Abstract of the Disclosure A wireless electronic device may include antenna structures and antenna tuning circuitry. The device may include a display mounted within a housing. A peripheral conductive member may run around the edges of the display and housing. Dielectric-filled gaps may divide the peripheral conductive member into individual segments. A ground plane may be formed within the housing. The ground plane and the segments of the peripheral conductive member may form antennas in upper and lower portions of the housing. The antenna tuning circuitry may include switchable inductor circuits and variable capacitor circuits for the upper and lower antennas. The switchable inductor circuits 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 associated with the upper antenna may be tuned to provide coverage in at least two low-band frequency ranges of interest.

Abstract: Electronic devices (10) are provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures (40). A parallel-fed loop antenna may be formed from portions of a conductive bezel and a ground plane (68). 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 (10). The bezel may contain a gap (18). Antenna feed terminals (58,54) for the antenna may be located on opposing sides of the gap (18). A variable capacitor (212) may bridge the gap (18). An inductive element (98) may bridge the gap and the antenna feed terminals (58,54). A switchable inductor (98') may be coupled in parallel with the inductive element (98). Tunable matching circuitry (M1) may be coupled between one of the antenna feed terminals (58) and a conductor in a coaxial cable (52) connecting the transceiver circuitry to the antenna.

Abstract: Handheld electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include antenna structures. An antenna may be located in an upper right corner of the handheld device as the handheld device is operated in a portrait mode. When the handheld device is rotated counterclockwise and operated in a landscape mode, the antenna is located in an unobstructed upper left corner of the device. The antenna may be formed from a strip of conductor. A proximal end of the strip of conductor may be connected to a transmission line. A distal end of the strip of conductor may be routed away from housing surfaces by bends formed in the strip. A printed circuit board in the handheld electronic device may have a hole. The distal end of the strip of conductor may be located adjacent to the hole.

Abstract: A cavity-backed antenna 26, or an electronic device, comprises a cavity-backed resonant antenna element 70 where the cavity 72 is formed from a dielectric support structure 112 covered with a layer of conductive material 74, 76. The dielectric material may be a moulded plastic support structure 112 with surfaces covered by a conductive metal such as copper or aluminium via any suitable deposition technique. The resonant antenna element 70 may take any form including one or more open and/or closed slot arrangements in a conductive plate or conductive layer formed on a printed circuit board, planar inverted-F antenna arrangements, patch antennas or various monopole and/or dipole printed antenna arrangements. The antenna may be arranged to operate in one or more different frequency bands. The cavity backed antenna 26 may be used in a housing associated with an electronic device such as a computer or a mobile phone. An antenna window may be provided in the said housing where the window may be formed by a region of dielectric material or from antenna window slots formed in a conductive member such as a conductive wall of the electronic device housing.

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.

Abstract: A handheld electronic device may be provided that contains wireless communications circuitry. The handheld electronic device may have a housing and a display. The display may be attached to the housing using a conductive bezel. The handheld electronic device may have one or more antennas for supporting wireless communications. A ground plane in the handheld electronic device may serve as ground for one or more of the antennas. The ground plane and bezel may define an opening. A rectangular slot antenna or other suitable slot antenna may be formed from or within the opening. One or more antenna resonating elements may be formed above the slot. An electrical switch that bridges the slot may be used to modify the perimeter of the slot so as to tune the communications bands of the handheld electronic device.

Abstract: Handheld electronic devices are provided that contain wireless communications circuitry having at least first and second antennas. An antenna isolation element reduces signal interference between the antennas, so that the antennas may be used in close proximity to each other. A planar ground element may be used as a ground by the first and second antennas. The first antenna may be formed using. a hybrid planar-inverted-F and slot arrangement in which a planar resonating element is located above a rectangular slot in the planar ground element. The second antenna may be formed from an L-shaped strip. The planar resonating element of the first antenna may have first and second arms. The first arm may resonate at a common frequency with the second antenna and may serve as the isolation element. The second arm may resonate at approximately the same frequency as the slot portion of the hybrid antenna.

Abstract: Handheld electronic devices are provided that contain wireless communications circuitry having at least one antenna. The antenna may have a planar ground element and a planar resonating element. The planar ground element may have a rectangular shape that matches a rectangular housing shape for a handheld electronic device. A dielectric-filled slot may be formed in one end of the planar ground element. The planar resonating element may be located above the slot. The antenna may be a hybrid antenna that contains both a slot antenna structure formed from the slot and a planar inverted-F structure formed from the planar resonating element and the planar ground element. The antenna may be fed using a single transmission line or two transmission lines. With two transmission lines, one transmission line may be associated with the slot antenna structure and one transmission line may be associated with the planar inverted-F antenna structure.
