Abstract: An antenna system includes a power divider, a first antenna array, a second antenna array, a third antenna array, a delay device, a first switch element, and a second switch element. The power divider has a first output port, a second output port, and a third output port. The first antenna array is coupled to the first output port. The second antenna array is coupled to the second output port. The third antenna array is coupled to the third output port. The first switch element determines whether to couple the first output port to the delay device according to a first control signal. The second switch element determines whether to couple the third output port to a ground voltage according to a second control signal.
