  • Publication number: 20190165467
    Abstract: A multi-antenna system uses non-radiation coupling edges to achieve isolation. A first radiation antenna, a second radiation antenna and at least one isolator are disposed on the surface of a substrate, wherein each of the first radiation antenna and the second radiation has a resonance radiating portion, a feeding portion, and at least one non-radiation coupling edge. The isolator is disposed between the first and second radiating antennas, extending from the non-radiation coupling edge of the first radiating antenna to that of the second radiating antenna. By disposing the isolator beside the non-radiation coupling edges, the near field coupling energy between the first and second radiating antennas is cancelled out, thereby improving the isolation of the antenna. By changing the length of the isolator, the resonant frequency of the system can be adjusted.
