Embodiment Construction

[0018] such as figure 1 The electronic device of the electronic device 10 may have a wireless communication circuit. The wireless communication circuitry can be used to support wireless communication in multiple wireless communication frequency bands.

[0019] The wireless communication circuitry may include one or more antennas. The antennas of the wireless communication circuitry 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 structures for the antenna may be formed from conductive electronic device structures.

[0020] The conductive electronic device structure may include a conductive housing structure. The housing structure may include peripheral structures, such as peripheral conductive structures extending around the periphery of the electronic device. The peripheral conductive structure may...

Abstract

An electronic device may have wireless circuitry with antennas. An antenna resonating element arm for a given antenna may be formed from metal structures supported by a plastic carrier. The antenna resonating element arm may be coupled to switching circuitry to isolate the antenna resonating element arm when the antenna resonating element arm is not being used to handle communications in a communications band. The electronic device may have a metal housing. A slot may separate a peripheral portion of the housing such as a sidewall portion from a planar rear portion. The sidewall portion and the planar rear portion may form an additional antenna that operates at communications frequencies outside of the communications band handled by the given antenna. A parasitic antenna resonating element arm may be formed in the slot to enhance the frequency response of the additional antenna.

Description

[0001] This application claims priority to US Patent Application 14 / 819,280, filed August 5, 2015, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates generally to electronic devices, and more particularly, to electronic devices having wireless communication circuitry. Background technique [0003] Electronic devices often include wireless circuitry with antennas. For example, cellular telephones, computers, and other devices often contain antennas to support wireless communications. [0004] Forming electronic device antenna structures with desired properties can be challenging. In some wireless devices, the presence of conductive structures, such as conductive housing structures, can affect antenna performance. Antenna performance may not be satisfactory if the housing structure is not properly configured and interferes with antenna operation. The size of the device also affects performance. Achieving a desi...
