Abstract

A handheld electronic device may be provided that contains wireless communications circuitry. The handheld electronic device may have a housing and a display. The display may be attached to the housing using a conductive bezel. The handheld electronic device may have one or more antennas for supporting wireless communications. A ground plane in the handheld electronic device may serve as ground for one or more of the antennas. The ground plane and bezel may define a opening. A rectangular slot antenna or other suitable slot antenna may be formed from or within the opening. One or more antenna resonating elements may be formed above the slot. An electrical switch that bridges the slot may be used to modify the perimeter of the slot so as to tune the communications bands of the handheld electronic device.

Description

[0001] This application claims priority to US Patent Application Serial No. 11 / 821,192, filed June 21, 2007. technical field

[0002] The present invention relates generally to wireless communication circuits, and more particularly to wireless communication circuits for handheld electronic devices with conductive bezels. 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 ...

Embodiment Construction

[0038] The present invention relates generally to wireless communications, and more particularly to wireless electronic devices and antennas for wireless electronic devices.

[0039] The antenna may be a small form factor antenna exhibiting wide bandwidth and high gain. According to an exemplary embodiment of the present invention, the antenna is configured such that it takes into account a conductive bezel on the wireless electronic device. The frame can be used as part of the antenna. For example, the bezel may form part of the antenna ground. The bezel may also perform mechanical functions, such as providing structural strength to the wireless electronic device. The bezel may secure a liquid crystal display (LCD) or other display to the surface of the wireless electronic device, using one suitable configuration that will be described herein as an example.

[0040]Wireless electronic devices may also be portable electronic devices, such as laptop computers, or small porta...
