Problems solved by technology
However, such a design method may cause additional coupling currents to be excited, which in turn will increase the correlation coefficient between adjacent antennas, which will increase the technical complexity of MIMO antenna array multi-band decoupling design
And there is an opportunity to increase the overall size of the multi-antenna array, so it is not easy to meet the MIMO antenna array design requirements that handheld communication devices must have high performance and miniaturization advantages at the same time, and it is not easy to overcome the technical difficulties of multi-band decoupling

Embodiment Construction
[0077] The present disclosure provides an example implementation of a multi-frequency multi-antenna array. The multi-frequency multi-antenna array includes a ground conductor plane and a dual-antenna array. The ground conductor plane separates a first side space and a second side space opposite to the first side space, and the ground conductor plane has a first edge. The dual antenna array is located on the first edge, and the dual antenna array has a maximum array length extending along the first edge. The dual antenna array also includes a first antenna and a second antenna. The first antenna is located in the first side space and includes a first resonant loop and a first radiating conductor line. The first resonant loop is connected in series by a first signal source, a first feeding conductor, a first capacitive coupling, a first resonant conductor, a first inductive grounding conductor and the first edge connected. The first radiation conductor line is electrically c...
