Description
[technical field]
The present invention relates to a kind of wireless lan antenna, particularly about a kind of wireless local area network broadband dual-band antenna.
[background technology]
In recent years, along with development of wireless communication devices, mobile terminal device uses more and more widely, and wireless lan (wlan) also becomes requisite function in the notebook computer.Along with IEEE802.11a (5.15～5.35GHz, 5.725～5.825GHz) and IEEE802.11b/g (proposition of 2.4～2.4835GHz) standards, WLAN has obtained fast development, and is meanwhile also more and more higher to the requirement of WLAN antenna.Require that its volume is little, in light weight, production and processing is convenient, reduce the antenna cost, on function, require simultaneously to use broadband and have the double frequency performance to meet the 802.11a/b/g standard-required to reach simultaneously.
Yet present employed antenna is mainly the PIFA antenna, because its frequency range relative narrower, thereby make the scope of application be restricted, can't adapt to the demand of market development.
In view of this, be necessary to design a kind of all channel antenna to satisfy the demand of existing market in fact to all channel antenna.
[summary of the invention]
The object of the present invention is to provide a kind of all channel antenna, thereby make the frequency range of antenna increase, to adapt to the demand of market development.
For achieving the above object, the invention provides a kind of wireless local area network broadband dual-band antenna, it comprises:
One substrate;
One antenna oscillator, it is located on the aforesaid substrate, and a rectangular channel also is set on this antenna oscillator meanders, and forms the multiple current loop;
One ground plate, it is located on the aforesaid substrate, and this ground plate one end extends outward a parasitic oscillator.
Thus, antenna miniaturization, two-band and wide band purpose have been realized by above-mentioned parasitic oscillator and meander technology.
Compared to prior art, wireless local area network broadband dual-band antenna provided by the present invention makes the frequency range of antenna increase, and has enlarged its scope of application, thereby has adapted to the demand of market development.
