Embodiment Construction

[0020] The present invention relates generally to electronic devices, and more particularly, to antennas for wireless electronic devices.

[0021] The wireless electronic device may be a portable electronic device such as a laptop computer, a tablet computer, a wireless access point base station such as an IEEE 802.11 base station, a plug-in repeater station such as for IEEE 802.11 communication, or an ultra-portable type of Small portable computer. Portable electronic devices may also be smaller devices. Examples of smaller portable electronic devices include wrist watch devices, pendant devices, earphone and earbud devices, and other wearable miniature devices. With one suitable arrangement, which is sometimes used here as an example, the portable electronic device may be a handheld electronic device.

[0022] Examples of portable handheld electronic devices include cellular telephones, media players with wireless communication capabilities, handheld computers (also someti...

Abstract

Dual slot antennas are provided for portable electronic devices such as handheld electronic devices. A dual slot antenna may have an open slot that has an open end that is not encircled by conductive material and may have a closed slot in which each end is surrounded by conductor. The closed and open slots may have portions that run parallel to each other. The antenna may be fed using feed terminals that bridge the closed and open slots in the vicinity of the portions of the slots that run parallel to each other. The slots may have portions that are angled with respect to each other. An end portion of one of the slots may be bent and widened for impedance matching and broadened bandwidth. Other portions of the slots may also be angled with respect to their main longitudinal axes.

Description

[0001] This application claims priority to US Patent Application No. 11 / 959,191, filed December 18, 2007, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to antennas, and more particularly, to antennas for portable electronic devices. Background technique [0003] Due in part to their mobile nature, portable electronic devices are often provided with wireless communication capabilities. Portable electronic devices may communicate with wireless base stations using wireless communications. For example, cellular telephones may communicate using the 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz cellular telephone frequency bands (eg, the primary Global System for Mobile Communications or GSM cellular telephone frequency bands). Portable electronic devices may also use other types of communication links. For example, portable electronic devices can use 2.4GHz and 5.4GHz Wi- (IEEE 802.11) frequency band and 2.4GHz ...
