A multi-antenna communication device is provided, including a grounding conductor plane separating a first side space and a second side space and having a first edge. A four-antenna array including first, second, third and fourth antennas is located at the first edge, and has an overall maximum array length extending along the first edge. The first and second antennas are located in the first side space, and the third and fourth antennas are located in the second side space. Each of the first to fourth antennas includes a feeding conductor line, a grounding conductor line, and a radiating conductor portion electrically connected to a signal source through the feeding conductor line and electrically connected to the first edge through the grounding conductor line, thereby forming a loop path and generating at least one resonant mode. The radiating conductor portion has a corresponding projection line segment at the first edge.

Multi-antenna communication device

An antenna array includes a ground conductor portion, a first antenna and a second antenna. The ground conductor portion has a first edge and a second edge. The first antenna has a first no-ground radiating area and a first feeding conductor portion. The second antenna has a second no-ground radiating area and a second feeding conductor portion. The first no-ground radiating area is formed and surrounded by a first grounding conductor structure, a second grounding conductor structure, and the first edge, and the first no-ground radiating area has a first breach. The second no-ground radiating area is formed and surrounded by a third grounding conductor structure, a fourth grounding conductor structure, and the second edge, and the second no-ground radiating area has a second breach. The first and second feeding conductor portions are respectively and electrically connected to a first signal source and a second signal source.
