1. A wideband antenna system, comprising:
a first metal radiation portion;
a second metal radiation portion, wherein the second metal radiation portion has a coupling distance with the first metal radiation portion, so that there is a coupling capacitor between the first metal radiation portion and the second metal radiation portion;
a first feeding contact, electrically connected to the first metal radiation portion and close to the coupling distance, wherein the first feeding contact is electrically connected to a radio frequency signal source;
a second feeding contact, electrically connected to the second metal radiation portion and close to the coupling distance;
a first ground contact, electrically connected to the second metal radiation portion;
a second ground contact, electrically connected to the first metal radiation portion;
an impedance tuner, electrically connected to the first feeding contact, the second feeding contact, the first ground contact, the second ground contact, and the radio frequency signal source, to switch the first metal radiation portion and the second metal radiation portion;
an aperture contact, electrically connected to the first metal radiation portion, so that the second ground contact is located between the first feeding contact and the aperture contact; and
an aperture tuner, electrically connected to the aperture contact.
