Various antennas and systems of antennas can benefit from meta-material construction. For example, avionics antennas including weather antennas may benefit from being constructed of meta-materials. A method includes electronically scanning, by an antenna of an aircraft, an environment of the aircraft. The electronically scanning includes transmitting or receiving an electrical frequency over the antenna. The antenna includes a negative index of refraction meta-material. The electronically scanning also includes applying an electric field to control a dielectric constant of the antenna. |
