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.

MIMO antenna for improved isolation

A Multiple-Input and Multiple-Output (MIMO) antenna having a plurality of isolation adjustment portions is provided. The MIMO antenna includes a plurality of radiation elements and a plurality of isolation adjustment portions. The plurality of radiation elements is symmetrically formed on the surfaces of the left and right sides of a dielectric element having a predetermined shape, is spaced apart from each other by a predetermined distance, operates in multiple frequency bands, and includes feeding portions, respectively. The plurality of isolation adjustment portions is coupled to the plurality of radiation elements so that they have electromagnetic characteristics different from those of the plurality of radiation elements, thereby improving isolation in each of the frequency bands in which the plurality of radiation elements operate.
