A novel structure of antenna includes a polar liquid, a container made of an insulating material and containing the polar liquid, and a feeder connected to the polar liquid contained in the container. Then, the polar liquid acts as a radiator. A wideband antenna includes a radiator constructed of a conductor having an electrical resonant length corresponding to a unique resonant frequency. The radiator having a feeder at one end connected to an outer circuit. A container made of an insulating material contains at least a portion of the radiator therein or disposed adjacent to a portion of the radiator, and a polar liquid contained inside the container affects electromagnetic flow of the radiator in order to change the unique resonant frequency of the radiator.
