Embodiment

[0017] like figure 1 As shown, this embodiment provides a printed circuit board, on which at least two antennas are arranged, in addition,

[0018] In the antennas on the printed circuit board, at least two adjacent antennas are provided with metal band gap structures in the clearance areas.

[0019] The structure, shape and number of layers of the metal bandgap structure are set according to the debugging requirements of the isolation between the adjacent antennas.

[0020] For example, as a preferred manner, the metal band gap structure may be a metal sheet array formed by a plurality of metal sheets arranged on the printed circuit board, and the metal sheet array included in the metal band gap structure may be a square shape array.

[0021] The number of layers of the metal bandgap structure may also be a multi-layer structure, which is set according to the design requirements of the isolation between the adjacent antennas.

[0022] Wherein, the metal sheet array is arra...

Abstract

The invention discloses a printed circuit board and a wireless terminal adopting a multiple-input multiple-output antenna technology. At least two antennas are arranged on the printed circuit board, and between the antennas on the printed circuit board, metal band gap structure are arranged in a clearance area of at least two neighboring antennas. By the printed circuit board and the wireless terminal adopting the multiple-input multiple-output antenna technology, isolation among the antennas is effectively improved, the problem about interference among the antennas is solved, and meanwhile, layout requirements of terminal products of cell phones and the like on multiple small-sized antennas are met.

Description

technical field [0001] The invention relates to the field of communications, in particular to a printed circuit board and a wireless terminal using a multiple-input multiple-output antenna technology. Background technique [0002] The multiple-input multiple-output (Multiple-Input Multiple-Out-put, MIMO) or multiple-transmitting-multiple-receiving antenna technology is a major breakthrough in the antenna technology in the field of wireless mobile communications. This technology can double the capacity and spectrum utilization of the communication system without increasing the bandwidth, and is a key technology that the new generation of mobile communication systems must adopt. MIMO technology allows multiple antennas to transmit and receive multiple spatial streams at the same time, with the ability to distinguish signals sent to or from different spatial orientations. The application of multi-antenna systems enables parallel data streams to be transmitted simultaneously. ...
