Embodiment Construction

[0030] The present invention relates generally to wireless communications, and more particularly to wireless electronic devices and antennas for wireless electronic devices.

[0031] The antenna may be a small form factor antenna exhibiting wide bandwidth and high gain.

[0032] A wireless electronic device may also be a portable electronic device, such as a laptop computer, or a small portable computer sometimes referred to as an ultraportable. Portable electronic devices may also be smaller devices. Examples of smaller portable electronic devices include wristwatch devices, pendant devices, headphone and earpiece devices, and other wearable miniature devices.

[0033] With one suitable arrangement, the portable electronic device is a handheld electronic device. Space is at a premium in handheld electronic devices, so a high-performance compact antenna can be particularly advantageous in such devices. Accordingly, the use of a handheld device is generally described herein ...

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.

Description

[0001] This application claims priority to US Patent Application No. 11 / 650,071, filed January 4, 2007. technical field [0002] The present invention relates generally to wireless communication circuits, and more particularly to wireless communication circuits for handheld electronic devices. Background technique [0003] Handheld electronic devices are becoming more and more popular. Examples of handheld devices include handheld computers, cellular phones, media players, and hybrid devices that include the functionality of multiple devices of this type. [0004] Due in part to their mobile nature, handheld electronic devices are often provided with wireless communication capabilities. Handheld electronic devices may utilize wireless communications to communicate with wireless base stations. For example, cellular telephones may communicate utilizing cellular telephone frequency bands at 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz (eg, the primary Global System for Mobile Com...
