Multi-element antenna structure with wrapped substrate

Abstract

Antennas are provided for electronic devices such as portable computers. Multiple resonating elements may be formed on a flexible antenna resonating element substrate. The flexible antenna resonating element substrate may have a first antenna resonating element at one end and a second antenna resonating element at an opposing end. The flexible antenna resonating substrate may be wrapped around a dielectric carrier and mounted within an electronic device under an inactive display region and above a dielectric housing window. Conductive structures such as conductive housing structures may form antenna ground. The resonating elements and antenna ground may form first and second antennas. A parasitic antenna resonating element may form part of the first antenna.

Description

[0001] This application claims priority to US Patent Application Serial No. 13 / 038,300, filed March 1, 2011, which is hereby incorporated by reference in its entirety. technical field [0002] This application relates generally to antennas, and more particularly to antennas for electronic devices. Background technique [0003] Electronic devices such as portable computers and handheld electronic devices often have wireless communication capabilities. For example, an electronic device may use long-range wireless communication circuitry such as cellular telephone circuitry and short-range communication circuitry such as wireless local area network communication circuitry. Some devices have the ability to receive other wireless signals such as GPS signals. [0004] It can be difficult to successfully incorporate antennas into electronic devices. Some electronic devices are manufactured with small form factors, so the space for antennas is limited. In many electronic devices,...
