陶瓷天线简介

 

 

陶瓷天线

陶瓷天线是一种用于通信、导航、雷达等领域的天线器件。它具有体积小、重量轻、频宽宽、耐温性好、抗干扰能力强等特点,被广泛应用于移动通信、卫星导航、飞行器等领域。下文以一款蓝牙天线为例,介绍其制造工艺流程。

1.陶瓷材料制备

      陶瓷材料的选择直接影响天线的性能指标。一般选用介电常数大,损耗小的瓷质材料。陶瓷材料的制备方式有多种,常见的有注浆成型法和压延成型法。本案例采用注浆成型法,即将陶瓷粉末与有机溶剂按一定比例混合后,注入模具中进行成型,再通过干燥、清洗等工艺步骤得到成品。

2.金属化处理

      陶瓷材料具有较好的介电性能,但其导电性能不足。因此,需要通过金属化处理提高导电性能。金属化处理一般采用化学镀银、真空蒸镀、电化学镀等方式。本案例采用化学镀银法。具体工艺流程如下:

(1)       清洗:将已经成型的陶瓷天线进行水洗、超声波清洗等工艺处理,出去表面杂质和油脂     

2)酸洗:将清洗好的陶瓷天线放入硝酸中进行酸洗,去除陶瓷表面的氧化层,并为后续步骤提供光洁表面

3)化学镀银:将经酸洗处理的陶瓷天线浸入含AgN03的银水中,经过还原反应后在陶瓷表面渡上一层粒子从而实现金属化处理。

3.组装配件

将金属化处理好的陶瓷天线,同其他金属组件(如中性点、馈线)进行组装。组装方式有焊接、粘接、压装等多种方式,本案例采用压装方式。将组件通过机械压力压合,形成一个整体,达到确保天线性能稳定的目的

4.组装完成后,需要对天线进行调试测试。测试内容主要包括天线增益、轴比、驻波比等多项指标。

下面为一例陶瓷天线各项测试数据示:
