Embodiment Construction

[0011] see figure 1 , a preferred embodiment of the present invention provides a wireless communication device 100, which can be a mobile phone, a personal digital assistant (PDA), a tablet computer, and the like. The wireless communication device 100 includes a radio frequency module 10 , a screw hole 20 , a matching circuit 30 and an antenna 40 .

[0012] The radio frequency module 10 is electrically connected to the antenna 40 through the screw hole 20 and the matching circuit 30 in turn, and the radio frequency module 10 is used for transmitting and receiving radio frequency signals from the antenna 40 .

[0013] The screw hole 20 is opened on the circuit board of the wireless communication device 100 , and is used for fixedly connecting the printed circuit board (PCB) of the wireless communication device 100 with the housing through an insulating screw. A conductive layer 21 and an insulating layer 22 are also disposed around the screw hole 20 , and the conductive layer ...

Abstract

The invention provides a wireless communication device, which comprises a radio frequency module, a screw hole, a match circuit and an antenna. The screw hole comprises a conducting layer. One end of the conducting layer is connected with the radio frequency module. The other end of the conducting layer is connected with the antenna through the match circuit. The conducting layer is used as a radio frequency test point of the wireless communication device. The screw hole replaces the radio frequency test point, so that the space and manufacture cost of a printed circuit board (PCB) are saved while the performance of the antenna is not affected.

Description

technical field [0001] The invention relates to a wireless communication device, in particular to a wireless communication device which saves a special radio frequency test point. Background technique [0002] Since the radio frequency performance of the wireless communication device is the key to the call quality of the wireless communication device, it is necessary to test the radio frequency performance of the wireless communication device when it leaves the factory. [0003] The existing test method is to set a radio frequency test point on the printed circuit board (Printed Circuit Board, PCB) of the wireless communication device, connect the radio frequency test point through a radio frequency tester, and use the radio frequency tester to test the radio frequency performance parameters of the wireless communication device ( Such as: receiving sensitivity, bit error rate, transmitting power, etc.) for testing. However, disposing radio frequency test points on the PCB i...
