AI Technical Summary

Benefits of technology

The design enables a compact, flexible antenna that can be mounted within wireless devices, providing stable electrical characteristics and supporting WWAN frequencies while maintaining independent grounding for enhanced performance.

Problems solved by technology

However, since the ground end of the antennas 11, 12 must be connected to the ground of the screen or the frame of the screen, the conventional antenna allocation is limited by the mounting position and cannot be freely adjusted.

Embodiment Construction

[0017]FIGS. 2A and 2B show allocation of the antenna in a notebook computer 2 according to the present invention. The antenna in the present invention can be used in various wireless electronic devices including, but not limited to, the notebook computer. Common electronic products such as PDAs may also use the antenna of the present invention to enable wireless communication. The notebook computer 2 has a screen 21 and a screen housing frame 22. The antenna 3 of the present invention (for example, the antenna 3 in the first embodiment, as shown in FIG. 3) is disposed in the screen housing frame 22 of the notebook computer 2, and a coaxial wire 23 connects the antenna 3 to a control circuit of the notebook computer 2, so as to transmit data through the antenna 3.

[0018]The antenna 3 has at least one fixing portion for fixing the antenna 3 to the screen housing frame 22. In this embodiment, the fixing portion is two through holes (including a first through hole 332 and a second throug...

Abstract

An antenna for WWAN is disclosed, which includes a first radiating metal strip, a second radiating metal strip, a first ground strip, a connecting metal strip and a second ground strip. The first radiating metal strip has a first portion and a second portion. The second radiating metal strip is independent. The first portion is coupled with the second radiating metal strip to induce a first resonance. The second portion cooperates with the second radiating metal strip to induce a second resonance. The connecting metal strip connects the first radiating metal strip to the first ground strip. The second ground strip is independent. The ground strips are used for grounding effect and can be selectively connected to a ground end of a wireless electronic device. Therefore, the antenna can be mounted in any place of the wireless electronic device, and has stable electrical characteristic.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an antenna for a wireless network, more particularly, to an antenna for WWAN.[0003]2. Description of the Related Art[0004]With the rapid development of the wireless communication technology, various multi-frequency communication products are put forward one after another, and thus the wireless communication products have become part of the daily life. Almost all new products are provided with wireless transmission function to meet the demands of the public. The notebook computer always needs data transmission which is simple in wiring and setting. In order to enable wireless transmission, an antenna is necessary. However, appearance, size, and performance are critical factors if notebook computers having wireless transmission function are to be widely accepted by the market. Therefore, better design and allocation of the antenna is important.[0005]In the conventional antenna allocation f...
