Plasma antenna

Ionized gas plasma antennas can be turned on and off and are good for stealth and resistance to electronic warfare and cyber attacks.

Ionized gas plasma antennas can eliminate or reduce co-site interference.

[4] Plasma silicon antennas are candidates for use in WiGig (the planned enhancement to Wi-Fi), and have other potential applications, for example in reducing the cost of vehicle-mounted radar collision avoidance systems.

Alternatively the plasma can be used as a reflector or a lens to guide and focus radio waves from another source.

[5] Solid-state antennas differ in that the plasma is created from electrons generated by activating thousands of diodes on a silicon chip.
