怎样装置WIFI天线

发布日期:2015-05-13 00:00 来源:http://hbkfit.com 点击:

  WIFI天线是别的一种适宜于蓝牙设备所运用的小型化天线。WIFI天线的品种可分为块状(Block)WIFI天线与多层(Multilayer)WIFI天线,前者是使用高温(摄氏1000度以上)将整块陶瓷体一次烧结完成后再将天线的金属部份印在陶瓷块的表面上;后者则采用低温共烧(LowTemperatureCofired)的方法将多层陶瓷迭压对位后再以800~900度的温度烧结,所以天线的金属导体能够依规划需求印在每一层陶瓷介质层上,如此一来便可有效减小天线所需尺度,并能到达隐藏天线规划布局的意图。

  因为陶瓷自身的介质常数较PCB电路板高,所以运用陶瓷当天线介质能有效减小天线尺度;在介质损耗(DielectricLoss)方面,陶瓷介质也比PCB电路板的介质损耗更小,所以非常适宜用在低耗电率的蓝牙模块运用。除此之外,当蓝牙模块有必要运用LTCC的技能来将模块体积降到最小时,LTCC蓝牙天线能够容易的与蓝牙模块整合在LTCC的多层陶瓷介质中,将是小型化蓝牙模块的最好挑选。
