Claim 13:
14. An antenna system, comprising
an antenna body;
a tunable component having a changeable operating parameter that is changeable, by a switch of the tunable component, between a capacitance and an inductance, wherein the antenna body is connected to the tunable component through a first connection point;
a parasitic element; and
a second filter, wherein:
the antenna body is connected to the second filter through the first connection point;
the second filter is connected in series between the antenna body and the tunable component in a manner that a first end of the second filter is connected to the antenna body and a second end of the second filter is connected to the tunable component;
the second filter presents a low impedance characteristic in a low frequency band, and presents a high impedance characteristic in a high frequency band;
the second end of the second filter is connected to ground through the tunable component;
the parasitic element is connected to the antenna body; and
the first end of the second filter is connected to the antenna body through the parasitic element.
