Abstract: An antenna system includes a signal feeding element, a first antenna element, a second antenna element, a first transmission line, and a second transmission line. The first antenna element is coupled to a first connection point. The second antenna element is coupled to a second connection point. The first transmission line is coupled between the signal feeding element and the first connection point. The second transmission line is coupled between the signal feeding element and the second connection point. The length of the second transmission line is substantially equal to that of the first transmission line. The first antenna element and the second antenna element substantially have opposite polarization directions. Therefore, the radiation pattern of the antenna system can provide a plurality of different gain peaks.
