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.
