Abstract
A high frequency antenna device is applied to an operation frequency band within a range of 20-45 GHz. The high frequency antenna device includes a substrate, an antenna array and a processing chip both respectively disposed on two opposite sides of the substrate, and two connectors mounted on the substrate. The antenna array includes a plurality of antennas arranged in at least one row. Each antenna is a dual-polarized metal sheet configured to be selectively operated in a horizontal polarization and a vertical polarization. The operation frequency band has a central frequency corresponding to a wavelength. Central points of any two adjacent antennas have an interval within a range of 0.25-0.75 times of the wavelength. The processing chip is electrically coupled to the antennas and the two connectors. The two connectors electrically correspond to the horizontal polarization and the vertical polarization of each of the antennas.
