可以理解的是，当在中框20上形成至少一个第一天线组件10的辐射体，既可以提高天线***的收发天线信号的性能，又可以避免在电子装置100的内部排布天线***，从而提高电子装置100的空间利用率。此外，当至少一个天线组件10形成在中框20上，可以避免当天线***排布于电子装置100内部时，电子装置100内部的器件对其产生电磁干扰。

如图2所示，电子装置100包括第六天线组件90。所述第六天线组件90收发频段为5G WIFI频段。第六天线组件90形成于中板22或形成于边框21。第六天线组件90与第五天线组件80形成2×2的5G WIFI多输入多输出***。
本实施例中，第六天线组件90具有多种设置方式：
实施方式一：如图16所示，边框21上设置有缝隙91。通过缝隙91分割出独立的一个第三金属区域92，第三金属区域形成第六天线组件90的辐射体。通过在边框21上直接形成第六天线组件90的辐射体，可以避免在电子装置100内额外设置第六天线组件90，从而减小电子装置100的内部空间，提高电子装置100的内部空间的利用率。在其他实施方式中，第六天线组件90也可以形成在第一短边211、第一短边212或第一长边213的其中一个。在其他实施方式中，通过微缝带分割出独立的一个第三金属区域92，第三金属区域形成第六天线组件90的辐射体。
实施方式二，与实施方式一不同的是：如图17所示，通过在中板22上天线支架40或第二天线支架50上固定柔性电路板或者通过激光直接成型技术或者印刷直接成型技术形成所述第六天线组件90。本实施方式中，通过在天线支架40的绝缘部41上粘贴柔性电路板以形成第六天线组件90的辐射体93。在其他实施方式中，也可以通过在天线支架40上嵌设或焊接等方式固定柔性电路板以形成第六天线组件90。再者，也可以通过激光直接成型技术或者印刷直接成型技术在天线支架40上形成金属天线图案，从而构成所述第六天线组件90。具体的根据实际情况设置。
以上是本申请的可选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
