Abstract

The invention relates to the technical field of communication equipment, in particular to an MIMO-embedded antenna system. The antenna system comprises a PCB, a camera antenna, a first microphone antenna, a first additional metal block antenna, a second additional metal block antenna, an SPK antenna, a USB antenna and a second microphone antenna; the bottom of the camera antenna is fixedly connected to the left upper portion of the top of the PCB; the bottom of the first microphone antenna is fixedly connected to the right upper portion of the top of the PCB; and the bottoms of the first additional metal block antenna and the second additional metal block antenna are fixedly connected to the left side and the right side of the middle of the top of the PCB respectively. According to the antenna system, a main radiation effect is generated by utilizing the PCB of the communication equipment, and capacitive energy coupling excitation PCB radiation sources can be the first additional metalblock antenna and the second additional metal block antenna in the communication equipment, so that the use of extra antenna space is avoided, and the cost and the design complexity of the antennae are greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, in particular to an antenna system with built-in MIMO. Background technique [0002] Communication equipment such as mobile phones and routers has become an indispensable tool in life. Due to the constraints of technology and performance, the components of communication equipment continue to constrain the evolution of appearance. The current communication equipment antennas use more and more frequency bands, resulting in its The number is also increasing, and the antenna needs more space to ensure the efficiency and bandwidth of each frequency band. In mobile phones, designers usually use the method of adding switches or tuners, so that the same antenna no longer works at a certain frequency. Instead, it can change the working frequency band with the change of the state of the auxiliary device, thus reducing the number of antennas and space requirements, but such a design ...
