1. An antenna system, comprising:
a signal feeding element;
a first antenna element, coupled to a first connection point;
a second antenna element, coupled to a second connection point;
a first transmission line, coupled between the signal feeding element and the first connection point; and
a second transmission line, coupled between the signal feeding element and the second connection point, wherein a length of the second transmission line is substantially equal to that of the first transmission line;
wherein the first antenna element and the second antenna element substantially have opposite polarization directions, such that a radiation pattern of the antenna system provides a plurality of different gain peaks;
wherein the antenna system covers an operational frequency band;
wherein a center-to-center distance between the first antenna element and the second antenna element is substantially equal to 0.64, 0.81 or 0.998 free-space wavelength of the operational frequency band.
