1. An antenna, comprising:
a housing having an internal cavity, the internal cavity having a bowl or cone shape and configured to contain an electrically conductive liquid, such that the electrically conductive liquid collects at least in a central bottom region of the bowl or cone shape of the cavity;
a feedline including a first feedline conductor and a second feedline conductor, and for connecting the antenna to a receiving and/or transmitting device, wherein the first feedline conductor is adapted to receive/transmit a signal from/to the conductive liquid; and
a conductive ground plane connected to the second feedline conductor.
