Antenna group and communication device

Abstract

The invention provides an antenna group and a communication device. The antenna group comprises neutralizing lines, a first antenna unit and a second antenna unit; the neutralizing line comprises first stubs and second stubs which are independently arranged; the first stubs are connected with the first antenna unit, and the second stubs are connected with the second antenna unit; the first stubs and the second stubs distributed elements; and the distributed elements include distributed inductors and / or distributed capacitors. According to the antenna group, the sectional neutralizing lines are adopted, the gaps and the wires of the neutralizing lines form the distributed elements, so that traditional lumped elements can be replaced, the decoupling of the antenna is realized, and a better decoupling effect and more optimized antenna performance are further provided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an antenna group and a communication device. Background technique [0002] With the advent of the 5G era, the frequency band and MIMO (Multiple-Input Multiple-Output) requirements of communication equipment are increasing, while the internal space of communication equipment such as mobile phones is becoming increasingly crowded. The test of design is getting tougher. In order to cope with the new frequency bands and MIMO requirements introduced by 5G technology, the number of antennas will inevitably increase. The distance between the antennas will become smaller due to the increasingly crowded internal space of the mobile phone and the increase in the number of antennas, which will lead to the deterioration of the isolation between the antennas and the ECC (Envelope correlation coefficient), which will affect the communication equipment. performance. To alleviat...

Problems solved by technology

However, as the performance of communication equipment such as mobile phones becomes more and more powerful, the layout on the PCB of communication equipment becomes more and more tense, and the neutralization line printed on the PCB board will occupy the space of the PCB, resulting in a decrease in the available space of the PCB.

In addition, the inherent loss of the lumped element used to tune the neutral line will also deteriorate the performance of the antenna
