Abstract
According to an embodiment, a wireless device includes an interposer, a semiconductor chip, and a non-conductor. The interposer comprises a plurality of conductor layers. The semiconductor chip is mounted on the interposer and comprising a built-in transceiver circuit. The non-conductor is placed on the interposer and seals the semiconductor chip. From among the plurality of conductor layers, a first conductor layer and a second conductor layer are symmetrically positioned with respect to center in a thickness direction of the interposer respectively have a first antenna conductor pattern and a second antenna conductor pattern. The first antenna conductor pattern and the second antenna conductor pattern respectively have a first opening and a second opening functioning as a slot antenna and have substantially equal area of a conductor portion. An orthogonal projection of the first opening onto the second conductor layer overlaps with the second opening.
