1. A multiple-input multiple-output (MIMO) antenna system, comprising:
a first antenna comprising a first radiator in a ring structure, and a second radiator disposed inside the first radiator, wherein the first radiator and the second radiator are not directly connected, and the first radiator and the second radiator are located on a first plane, wherein the first antenna comprises at least two inductor components, one end of an inductor component of the at least two inductor components is connected to the first radiator, and the other end of the inductor component is connected to the second radiator, and wherein a first feed is further disposed on the first antenna, one end of the first feed is disposed on the second radiator; and
a second antenna comprising a third radiator in a ring structure, wherein at least two slots are disposed on the third radiator, and the at least two slots penetrate inside and outside of the ring structure of the third radiator, wherein the third radiator is disposed in the first plane, and wherein a second feed is further disposed on the third radiator, and the second feed is serially connected to a middle portion of the third radiator between any two adjacent slots of the at least two slots,
wherein the first antenna is disposed inside the second antenna, and the first antenna and the second antenna are not connected to each other.
