1. An antenna system, comprising:
an antenna body having one or more connection points between the antenna body and a ground;
a tunable component having a changeable operating parameter that is changeable, by a switch of the tunable component, between a capacitance and an inductance; and
a second filter, wherein the antenna body is connected to the second filter through a first connection point;
wherein 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, and wherein the second filter presents a low impedance characteristic in a low frequency band, and presents a high impedance characteristic in a high frequency band; and
wherein the second filter is connected to the ground through the tunable component.
