在一些实施例中，第四辐射枝节14包括第五辐射部141和第六辐射部142，第五辐射部141和第六辐射部142呈L型，第五辐射部141用于与第一辐射枝节11连接，第六辐射部142用于焊接在金属地板20上与加载组件30电性连接；第五辐射枝节15包括第七辐射部151和第八辐射部152，第七辐射部151和第八辐射部152呈L型，第七辐射部151用于与第一辐射枝节11连接，第八辐射部152用于焊接在金属地板20上与馈源连接；同样，本实施例中将第四辐射枝节14和第五辐射枝节15设置为L型，以便于第四辐射枝节14和第五辐射枝节15与金属地板20进行焊接。
请参阅图5，图5为本申请实施例提供的天线装置中设置加载组件30前后的回波损耗对比示意图。加载前的回波损耗曲线如图5中的A曲线所示，加载后的回波损耗曲线如图5中的B曲线所示，依据图中可知，该天线装置在设置加载组件30之间在不同频点的回波损耗可下降5dB～22dB。
请参阅图6，图6为本申请实施例提供的天线装置中设置加载组件30前后的驻波比对比示意图。加载前的驻波比曲线如图6中的C曲线所示，加载后的驻波比曲线如图6中的D曲线所示，依据图中可知，若天线装置为设置加载组件30即在设置加载组件30之前的辐射频率范围为2.41GHz-2.50GHz；而设置加载组件30之后即加载后的天线装置的辐射频率范围为2.36GHz-2.54GHz，对比可知，本申请中通过设置加载组件30能够有效扩展带宽，以便于提高天线装置的性能。
本申请还提供了一种终端设备，该终端设备包括上述的天线装置，该天线装置在终端设备中可以作为收发一体的天线装置，由于对该天线装置
进行了详细说明，此处不再赘述。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的天线装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
