Abstract: A second slit 117 and a fourth slit 119 provided in a first antenna element 150 and a first slit 116 and a third slit 118 provided in a second antenna element 151 are adjusted such that the mutual coupling between the first antenna element 150 and the second antenna element 151 in 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.
