Plasma Antennas

A plasma antenna uses ionized gas (plasma) to transmit and receive radio signals. Unlike traditional metal antennas, plasma antennas can be turned on and off quickly, are less detectable, and can change shape or frequency easily. When electrical energy is applied, it creates a plasma, which interacts with radio waves similarly to metal, allowing communication. Once powered down, the plasma dissipates, making the antenna temporarily inactive. This technology is useful in military, industrial, and secure communications due to its versatility, reconfigurability, and potential for stealth.
