Abstract:
1. A MIMO antenna system having a multi-band characteristic, comprising: a circuit board including two pairs of power feeders; a pair of carriers arranged in both sides of the circuit board; a first antenna pattern corresponding to a first band and a second antenna pattern corresponding to a second band, which are connected to the power feeders and are formed in one of the carriers; a third antenna pattern corresponding to the first band and a fourth antenna pattern corresponding to the second band, which are connected to the power feeders and are formed in the other carrier; and a first coupling antenna part which is formed in the one carrier and operates with the first band and a second coupling antenna part which is formed on the other carrier and operates with the second band, the first and second coupling antenna parts being separated from each other on the carriers on which the antenna patterns are formed.
