Abstract
A second slitand a fourth slitprovided in a first antenna elementand a first slitand a third slitprovided in a second antenna elementare adjusted such that the mutual coupling between the first antenna elementand the second antenna elementin the desired frequency band is canceled, and reduces degradation in coupling between antenna elements without connecting the antenna elements through components and the like. With such a configuration, it is possible to achieve high-efficiency loosely coupled MIMO array antennas operating in the same frequency band in a portable wireless terminal.
