Abstract
A MIMO antenna for improving isolation is disclosed. The disclosed antenna includes a dielectric feature; a ground plane included in a first layer of the dielectric feature; a first radiator, which is electromagnetically joined with a first feed point, configured to radiate a first RF signal, and joined with the ground plane; a second radiator, which is electromagnetically joined with a second feed point, configured to radiate a second RF signal, and joined with the ground plane; and a connector line, which is joined with a particular point of the first radiator and with a particular point of the second radiator to connect the first radiator with the second radiator. The disclosed antenna can improve isolation properties between multiple antennas and can ensure adequate isolation properties even when the distances between multiple antennas are set to be relatively small.
