Abstract
A first connection circuit () is adjusted to cancel out mutual coupling impedance occurring between a first antenna element () in a first frequency band and a second antenna element () in a second frequency band, and reduces a degradation occurring due to the coupling between the antenna elements. A second frequency band cutoff circuit () for the second frequency band is provided between the first antenna element () and the first feeding portion ().
