Abstract
The utility model provides a high gain USB WLAN (wireless local area network) card, comprises an external antenna, an SMA connector, an RF module, a main control chip and a built-in antenna, wherein the RF module is connected with the SMA connector; the main control chip is connected with RF module; and the built-in antenna is connected with the RF module. The high gain USB WLAN card realizes the 300M high gain effect through a built-in PIFA antenna and an external omnidirectional antenna, and avoids mutual interference of the built-in antenna and the external antenna, and reduces the bearing weight to the antenna of the product and guarantees that the USB interface has contact reliability simultaneously.
Description
Technical field
The utility model relates to the wireless network card field, relates in particular to a kind of high-gain USB wireless network card.
Background technology
Along with the develop rapidly of mechanics of communication in modern age, wireless communication technique has also obtained significant progress, and a kind of new wireless data communication technology that WLAN gets up as new development is also progressively full-fledged.Wireless network card is as indispensable parts in the wireless local area network (WLAN) system, and its application and development prospect and market are also good day by day.
Existing 300M high-gain wireless network card uses two external antennas, can produce interference each other, and the sagging weight of two antennas can cause the USB interface loose contact simultaneously, and the serious USB interface that causes damages.
The utility model content
The purpose of the utility model is to provide a kind of high-gain USB wireless network card, realizes 300M high-gain effect through the external omnidirectional antenna of a built-in PIFA antenna and, and avoids the mutual interference mutually of built-in aerial and external antenna.
Another purpose of the utility model is to provide a kind of high-gain USB wireless network card, can alleviate the bear weight of product to antenna through a built-in PIFA antenna and an external omnidirectional antenna, guarantees that the USB interface contact is reliable.
The purpose of the utility model realizes through following technical scheme.
A kind of high-gain USB wireless network card comprises external antenna, SMA connector, the RF module that is connected with the SMA connector, and the main control chip that is connected with the RF module also comprises the built-in aerial that is connected with said RF module.
Preferably, also comprise the USB interface that is connected with said main control chip.
Preferably, said USB interface is a device I/O interface module, is standard USB interface.
Preferably, said external antenna is an omnidirectional antenna, and said built-in aerial is the PIFA antenna.
The utility model compared with prior art; Have the following advantages: the utility model is realized 300M high-gain effect through a built-in PIFA antenna and an external omnidirectional antenna; And avoid the mutual interference mutually of built-in aerial and external antenna; Alleviate the bear weight of product simultaneously, guarantee that the USB interface contact is reliable antenna.
Description of drawings
Fig. 1 is the utility model high-gain USB wireless network card theory diagram.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Figure 1ly, high-gain USB wireless network card comprises: the SMA connector that is connected with external omnidirectional antenna, the RF module that is connected with the SMA connector, and the main control chip that is connected with the RF module.Simultaneously, in not having the card network interface card, also comprise built-in PIFA antenna (Planar Inverted F-shaped Antenna, planar inverted F-shape antenna) that links to each other with the RF module and the USB interface that links to each other with main control chip.
Wherein, USB interface is called device I/O interface module, is standard USB interface.
Above-mentioned SMA connector can pivot, thereby said external omnidirectional antenna can rotate, with the polarization angle of adjustment antenna.
The utility model is realized 300M high-gain effect through built-in PIFA antenna and an external omnidirectional antenna, and avoids the mutual interference mutually of built-in aerial and external antenna, alleviates the bear weight of product to antenna simultaneously, guarantees the USB interface contact reliably.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
