Abstract
An antenna 300 comprising a housing 310 with an internal cavity 315. The cavity 315 holds an adjustable amount of electrically conductive liquid, and a twin-conductor feedline 350 connects the antenna 300 to a receiving and/or transmitting device. The conductive liquid in the cavity 315 of the antenna housing 310 acts as a first element and receives/transmits signals from/to the first feedline conductor, whilst the second feedline conductor is attached to electrical ground 320.
