To achieve the identification of the fast-moving tag groups, a 3 × 4 Butler matrix is utilized to switch the radiation directions at −25°, 0°, and +25°, respectively. Besides, series-fed patch antenna element is designed and the 1 × 4 antenna array is built with element rotation for a good polarization performance. Finally, the proposed antenna system is fabricated and the identification area and radiation performance are tested.
