 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
在本实施例中，提供了一种PCB天线，该天线具有多频段功能，可实现5G频段下790-960MHz、1710-2690MHz、3.3-3.6GHz和4.8-5GHz频段信号辐射，覆盖5G_Sub6G频段的信号辐射。
参见图1-4，给出了一种PCB天线的示意图。
该PCB天线10包括PCB基板11、以及设置在所述PCB基板11上的第一辐射部100和第二辐射部200。
在一个优选的实施例中，如图1所示，PCB基板11的尺寸为124.65mm×27.02mm，厚度为0.8mm。该PCB基板的体积小，占用终端设备的空间小。
进一步的，第一辐射部100与第二辐射部200之间相对设置，二者之间存在缝隙，未直接连接。
第一辐射部100包括第一辐射体101以及由第一辐射体101延伸出的第二辐射体102和第三辐射体103。第二辐射体102与第三辐射体103相对于第一辐射体101沿第一方向401上的轴线500对称设置，第二辐射体102、第三辐射体103之间形成馈电槽301，第一方向401为第二辐射体102相对于第一辐射体101的延伸方向。第二辐射体102和第三辐射体103与第一辐射体101连接的相对侧分别设置有第一开口1001和第二开口1002。
为方便说明，在本实施例中，将第一方向401设定为水平方向的从右至左的方向，与第一方向相反的方向为水平方向上的从左至右的方向。
也就是说，如图2-4所示，第一辐射体101的左侧设置有第二辐射体102和第三辐射体103，从第一辐射体101的左侧延伸，沿水平方向从左至右延伸一定长度形成第二辐射体102和第三辐射体103。第二辐射体102和第三辐射体103。相对于第一辐射体101在水平方向上的轴线是对称设置的，且二者之间存在缝隙，该缝隙即为馈电槽301。第二辐射体102的左侧设置有第一开口1001，第三辐射体103的左侧设置有第二开口1002，且第一开口1001和第二开口1002相对于第一辐射体101在水平方向上的轴线是500对称设置的，且开口大小一致。
如图2-4所示，第二辐射部200包括第四辐射体204以及由第四辐射体204在水平方向上延伸出的第五辐射体205和第六辐射体206，第五辐射体205向右延伸至馈电槽301，且与第一辐射体101之间存在第一缝隙302；第六辐射体206沿第四辐射体204向左延伸。

进一步的，第二辐射部200还包括所述第十辐射体210沿所述第一方向401的相反方向延伸出的第十二辐射体212，所述第十一辐射211体沿所述第一方向401的相反方向延伸出的第十三辐射体213，第十二辐射体212和第十三辐射体213相对于第一辐射体101在水平方向上的轴线是对称设置的，且第十二辐射体212的上侧（远离第十三辐射体213的一侧）与第十辐射体210的上侧（远离第十一辐射体211的一侧）是对齐的，第十三辐射体213的下侧（远离第十二辐射体212的一侧）与第十一辐射体211的下侧（远离第十辐射体210的一侧）是对齐的。

进一步的，在本实施例中，为了增强PCB天线在中高频段的谐振表现，第三缝隙304的宽度和第四缝隙305的在水平方向上的尺寸为2.3-2.7mm，例如，可以设置为2.5mm，即第一辐射部100与第二辐射部200之间的耦合距离可以设置2.5mm。通过特定的耦合距离来增强天线在中高频段的谐振表现，提高天线性能。
在另一个可选的实施例中，参见图2-4，第十辐射体210和第十一辐射体211靠近第五辐射体205的一侧、靠近第四辐射体204分别设置有第三开口2003和第四开口2004，第三开口2003和第四开口2004相对于第一辐射体101在水平方向上的轴线是对称设置的。另外，第十辐射体210和第十一辐射体211相对于远离第七辐射体207的一侧靠近第七辐射体207分别设置有第五开口2005和第六开口2006，第五开口2005和第六开口2006相对于第一辐射体101在水平方向上的轴线是对称设置的。其中，第三开口2003、第五开口2005设置在第十辐射体210上，第四开口2004、第六开口2006设置在第十一辐射体211上，且第三开口2003在第五开口2005的左侧，第四开口2004在第六开口2006的左侧。

进一步的，PCB天线10还包括馈电端口600，设置于第一缝隙302。馈电端口302包括与第一辐射体101连接的一端和与第五辐射体205连接的另一端，并且该馈电端口600的馈电方式可以是同轴馈电。
