Abstract | The invention provides a high-isolation dual-mode ultra-wideband MIMO (Multiple-Input Multiple-Output) antenna. According to the antenna, a microstrip feeder (2) made of metal copper foil, a circularcoupling structure (4) and a through hole short-circuit structure (3) are arranged on the lower surface of a dielectric substrate (7); a coplanar waveguide feeder (1) and a radiation unit (6) are connected and located in the middle of the antenna, and an impedance matching structure (5) is located between the coplanar waveguide feeder (1) and the radiation unit (6); and the microstrip feeder (2) is connected with the circular coupling structure (4), and the through hole short-circuit structure (3) is connected with the two sides of the dielectric substrate (7). Since two antenna transition structures and a radiation patch structure are shared, the design of a compact structure is realized; and high isolation is realized between two feed ports of the antenna, so that it is not needed to adda decoupling structure.
