Abstract
An antenna device includes a carrier and an antenna array. A first dual-frequency antenna structure of the antenna array includes a first conductive sheet, a first transmitting antenna, and a first receiving antenna. A first extension line passes through both two centers of two regions defined by respectively and orthogonally projecting the first transmitting antenna and the first receiving antenna onto the first conductive sheet. A second dual-frequency antenna structure of the antenna array includes a second conductive sheet, a second transmitting antenna, and a second receiving antenna. A second extension line passes through both two centers of two regions defined by respectively and orthogonally projecting the second transmitting antenna and the second receiving antenna onto the second conductive sheet. The first and second conductive sheets have a four-fold rotational symmetry relative to an intersection point between the first extension line and the second extension line.
