Abstract: A multi-input multi-output antenna system capable of being disposed in an electronic device and the electronic device including the antenna system have a low-frequency antenna assembly and a high-frequency antenna assembly. The low-frequency antenna assembly includes multiple low-frequency antennas that are spaced apart from each other by a distance. The high-frequency antenna assembly includes multiple high-frequency antennas that are spaced apart from each other by a distance. One of the high-frequency antennas is structured as a low-profile dish antenna and is located between the low-frequency antennas, so that the antenna system has smaller volume and height, and better isolation and radiation patterns.

Abstract: An antenna assembly with compact layout traces includes a circuit board and at least one wireless antenna unit, wherein the circuit board is provided with an antenna module, the at least one wireless antenna unit can be located at the same edge or at different edges of the circuit board, each of the at least one wireless antenna unit includes two antennas of the planar inverted-F antenna (PIFA) structure and a neutralization line, and the two antennas are spaced apart from each other and the two ends of the neutralization line are electrically connected to and overlap the two antennas respectively. By arranging antennas of the same working band along the same edge of the circuit board, the corresponding layout traces can be effectively shortened.

Abstract: A low-profile dual-band high-isolation antenna module is fixed on a substrate and includes two high-frequency antennas and two low-frequency antennas located on two opposite sides of the substrate respectively. The bottom ends of the low-frequency antennas are connected to a grounding of the substrate. A decoupling element is disposed between the high-frequency antennas and the low-frequency antennas. The top end of each high-frequency antenna forms a bent portion, and so does the top end of each low-frequency antenna. The decoupling element has two ends extending to positions corresponding respectively to the low-frequency antennas but is not in contact with the low-frequency antennas or the high-frequency antennas. The bottom end of the decoupling element is connected to the grounding through at least one metal strip. The bent portions effectively reduce the space occupied by the antennas while the decoupling element provides isolation between the antennas.
