    • Embodiments of the present invention provide a wireless terminal including a PCB, an antenna, and a data connector. The PCB has a groove, which divides the PCB into a first part and a second part. The second part is connected to the antenna, the first part is connected to the data connector through a rotating shaft, and connecting wires of the data connector are connected to the second part. The first part and the second part each have a ground. The ground of the first part is connected to a metal casing of the data connector, and a ground wire of the data connector is connected to the ground of the second part and the ground wire of the data connector is electrically connected to the metal casing of the data connector. In the embodiments of the present invention, a groove is formed by cutting on the PCB to divide the PCB into two parts so as to produce a distributed capacitance effect and the connecting wires of the data connector may produce a distributed inductance effect, so that a resonant circulating current is formed. In this way, the electromagnetic radiation capability of the PCB is enhanced, and further the radiation capability of the entire wireless terminal is enhanced, so that the radio performance of the wireless terminal is improved.
    • 本发明的实施例提供了一种包括PCB,天线和数据连接器的无线终端。 PCB有一个凹槽,将PCB分成第一部分和第二部分。 第二部分连接到天线,第一部分通过旋转轴连接到数据连接器,并且数据连接器的连接线连接到第二部分。 第一部分和第二部分各有一个地面。 第一部分的地线连接数据连接器的金属外壳,数据连接器的地线连接第二部分的地线,数据连接器的地线电连接到数据连接器的金属外壳 数据连接器。 在本发明的实施例中,通过在PCB上切割形成凹槽以将PCB分成两部分以产生分布电容效应,并且数据连接器的连接线可以产生分布电感效应, 形成谐振循环电流。 这样,增强了PCB的电磁辐射能力,进一步提高了整个无线终端的辐射能力,从而提高了无线终端的无线性能。
