Embodiment Construction

[0056] The present invention will be fully understood from the following embodiments, so that those skilled in the art can implement the present invention, but the implementation of the present invention should not be limited by the following embodiments.

[0057] 1 to 3 are schematic structural diagrams of dual-band antennas according to embodiments of the present invention. For the convenience of those skilled in the art, the three-dimensional structure of the dual-frequency antenna of the present invention can be fully understood by comparing Figs. For the directions of each dimension in , let the directions pointed by x, y and z be positive, and the directions opposite to the directions pointed by x, y and z be negative, so the directions opposite to the directions of the arrows of x, y and z are represented by - x, -y and -z represent.

[0058] FIG. 1 is a schematic structural diagram of a dual-band antenna 100 according to a first embodiment of the present invention, wh...

Abstract

The invention provides a dual-band antenna comprising an impedance matching control element, a first radiating element and a second radiating element, wherein the impedance matching control element comprises a first end and a second end; the first radiating element is used for operating a first band; the first radiating element is electrically connected to the first end of the impedance matching control element; the first radiating element extends along the oblique direction forming an obtuse angle relative to the joint; the second radiating unit is used for operating the second band; the second radiating element comprises a first extension part which is electrically connected to the second end of the impedance matching control element; and the first extension part extends along the opposite oblique direction forming an obtuse angle relative to the joint.

Description

technical field [0001] The invention relates to an antenna, in particular to a dual-band stereo antenna. Background technique [0002] With the rapid development of science and technology, various hand-held electronic devices or wireless transmission devices, such as mobile phones, notebook computers, personal digital assistants (PDA for short), and wireless AP access devices, are becoming more and more popular. In order to give full play to the wireless communication function of the above-mentioned handheld devices, various small, portable and effective antennas have been continuously developed, and they conform to various wireless communication standard frequencies, such as IEEE 802.11a (5GHz), IEEE 802.11b / g (2.4GHz) ), IEEE 802.11n (5 and / or 2.4GHz), Bluetooth (2.4GHz), and Worldwide Interoperability for Microwave Access (WiMAX, mainly 2.3, 2.5 and 3.5GHz), etc. [0003] In order to meet the above requirements, various types of small antennas have been continuously impr...
