Embodiment Construction

[0024] Electronic devices may be provided with wireless communication circuitry. Wireless communication circuitry may be used to support wireless communication in multiple wireless communication frequency bands. Wireless communication circuitry may include one or more antennas.

[0025] The antennas may include loop antennas, inverted-F antennas, strip antennas, planar inverted-F antennas, slot antennas, hybrid antennas including more than one type of antenna structure, or other suitable antennas. If desired, conductive electronic device structures may be used to form the conductive structures for the antenna. The conductive electronic device structure may include a conductive housing structure. The housing structure may include a peripheral conductive member extending around a periphery of the electronic device. The peripheral conductive features may serve as a frame for a planar structure such as a display, may serve as a sidewall structure of a device housing, or may for...

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.

Description

[0001] This application claims priority to US Patent Application No. 13 / 041,905, filed March 7, 2011, which is hereby incorporated by reference in its entirety. technical field [0002] The present application relates generally to wireless communication circuits, and more particularly to electronic devices having wireless communication circuits. Background technique [0003] Electronic devices such as portable computers and cellular telephones are often provided with wireless communication capabilities. For example, an electronic device may use long-range wireless communication circuitry such as cellular telephone circuitry to communicate using cellular telephone frequency bands of 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, and 2100 MHz. Electronic devices may handle communications with nearby devices using short-range wireless communication links. For example, electronic equipment can use 2.4GHz and 5GHz (IEEE802.11) frequency band and 2.4GHz frequency band communications. ...
