Abstract: An antenna array device provided, which includes a substrate, multiple antenna elements, a metal ground plate and a first isolation unit group. The multiple antenna elements are disposed on a first surface of the substrate. The multiple antenna elements have a first polarization direction and a second polarization direction opposite to the first polarization direction. The first isolation unit group is disposed between adjacent two of the multiple antenna elements. An arrangement direction of the first isolation unit group is perpendicular to the first polarization direction and the second polarization direction. The first isolation unit group is two isolation units which are adjacent, each of which comprises an outer end and an inner end opposite to the outer end. The inner end is connected to the metal ground plate disposed on a second surface of the substrate via a second via.

Abstract: The present disclosure relates to a beamforming device, including a transceiver circuit, a switch circuit and a beam former. The switch circuit is electrically connected to the transceiver circuit. The beam former contains a plurality of antenna units. The antenna units receive and send signals according to multiple radiation angles, and the radiation angle of each antenna unit is different. The switch circuit selectively conducts one of the antenna units to the transceiver circuit according to a control signal.

Abstract: A control method of a power factor correction circuit is provided. The first operating frequency of the power factor correction circuit is controlled to less than one-third of the minimum limitation frequency, the first operating frequency is controlled to less than 1−Nth of the first suppression frequency, and the second operating frequency of the power factor correction circuit is controlled to less than 1−Nth of the second suppression frequency. Consequently, at least portion of the operating frequency of the power factor correction circuit is not in the range measured by the machine so as to reduce the value of the noise of the electromagnetic interference.

Abstract: A dual polarized antenna includes a first antenna unit and an isolated band gap. The first antenna unit is formed on the dielectric board, and the first antenna unit being conducted is configured to receive or transmit a signal with each of a first polarization direction and a second polarization direction. The isolated band gap is formed on the dielectric board and is disposed adjacent to the first antenna unit. It forms a first included angle which is neither 0° nor 90° between the first polarization direction and the isolated band gap.
