Problems solved by technology

However, the electromagnetic wave fields radiated by the LTE antenna and other antennas in the wireless communication device are likely to interfere with each other, which increases the envelope correlation coefficient (Envelope Correlation Coefficient, ECC) between the LTE antenna and other antennas, which in turn leads to The error rate of demodulated information increases

Embodiment Construction

[0011] see figure 1 A preferred embodiment of the present invention provides a wireless communication device 100, which may be a terminal such as a mobile phone or a tablet computer.

[0012] The wireless communication device 100 includes a circuit board 10 , a main antenna 30 , a secondary antenna 50 and a metal piece 70 . The main antenna 30 , the secondary antenna 50 and the metal piece 70 are all disposed on the circuit board 10 . The main antenna 30 and the auxiliary antenna 50 constitute a multiple input and multiple output (Multiple Input Multiple Output, MIMO) antenna architecture, so that the main antenna 30 and the auxiliary antenna 50 can work normally at the same time.

[0013] The circuit board 10 includes a short side 12 and a long side 14 vertically connected to the short side 12 . The short side 12 defines a first notch 122 , and the long side 14 defines a second notch 142 . On the circuit board 10, a signal feed point 16 and a ground point 18 are set adjace...

Abstract

The invention provides a wireless communication device which comprises a circuit board, a metal part, and a main antenna and an auxiliary antenna which are arranged on the circuit board, wherein a main current direction of the main antenna is perpendicular to a main current direction of the auxiliary antenna; the metal part is arranged on the circuit board; the metal part and the auxiliary antenna are spaced apart from each other; and current on the auxiliary antenna is coupled to the metal part to allow the maximum radiation fields of the auxiliary antenna and the main antenna to be perpendicular. The wireless communication device can reduce an envelope correlation coefficient (ECC) between the auxiliary antenna and the main antenna.

Description

technical field [0001] The present invention relates to a wireless communication device, in particular to a wireless communication device with a dual-antenna architecture. Background technique [0002] In recent years, the Long Term Evolution (LTE) technology has become increasingly mature, and the LTE antenna has undoubtedly become one of the most important components in a wireless communication device. The transmission technology mainly used by the LTE antenna is multiple input and multiple output (Multiple Input Multiple Output, MIMO) technology. However, the electromagnetic wave fields radiated by the LTE antenna and other antennas in the wireless communication device are likely to interfere with each other, which increases the envelope correlation coefficient (Envelope Correlation Coefficient, ECC) between the LTE antenna and other antennas, which in turn leads to The error rate of demodulated information increases. Contents of the invention [0003] In view of the ...
