智能天线是怎样炼成的?天线是无源器件,按波瓣角度区分,有全向天线和定向天线两种:全向天线通常覆盖角度大,但覆盖距离较近;定向天线覆盖距离虽然远,但却是以牺牲覆盖角度为代价的。那么有没有一种天线,既能全方位覆盖各个角度,又能在每个角度都获得更远的覆盖距离呢?——答案是肯定的,那就是智能天线。先来分析一下在WLAN系统中,全向天线和定向天线在使用时有哪些不足,或者是需要改进的地方。
Antenna is made of passive? Antenna is passive components, according to the angle of the lobe, there are two kinds of omnidirectional antenna and directional antenna: omnidirectional antenna usually covering a large angle, but covering a short distance; although the distance covered by the directional antenna , But at the expense of coverage. So is there an antenna that can cover all angles in all directions and achieve a wider range of coverage at each angle? - The answer is yes, that is, a smart antenna. First to analyze the WLAN system, the omnidirectional antenna and directional antenna in use, what are the deficiencies, or need to be improved.
