摘要： According to one embodiment, an antenna device includes a branch circuit, a first phase shifter, a second phase shifter and a radiating element. The branch circuit divides an input signal and generates a first signal and a second signal. The first phase shifter is capable of shifting a phase of the first signal. The second phase shifter is capable of shifting a phase of the second signal. The radiating element transmits a right-hand circularly polarized wave based on a first output signal of the first phase shifter and transmits a left-hand circularly polarized wave based on a second output signal of the second phase shifter.

摘要： According to an embodiment, a wireless device includes an interposer, a semiconductor chip, electrodes, and a slot antenna. The interposer includes conductive layers disposed at least at a side of a component mounting surface and a side of a reverse surface opposite to the component mounting surface. The semiconductor chip is mounted on the component mounting surface and includes a built-in transceiving circuit. The electrodes are disposed in a conductive layer disposed at the side of the reverse surface of the interposer so as to be electrically connected to an outside of the wireless device. At least a portion of the slot antenna is disposed in at least one of the conductive layers of the interposer. A shortest distance between an end in a width direction of the slot antenna and the electrodes is smaller than a sum of a minimum line width and a minimum line space of the interposer.
