Advantages of plasma antennas

 1. An important advantage of plasma antenna over a conventional antenna is that the former is much lighter. Based on a set of patented beam-forming technologies, these high-performance electronically-steerable antennas are extremely lightweight and compact.

2. Free from mechanical parts, these maintenance-free plasma antennas are ideally suited for a wide range of wireless communications and sensing applications.

3. Plasma antennas have a number of potential advantages for antenna design. These are reconfigurable. When one plasma antenna is de-energised, the antenna reverts to a dielectric tube, and a second antenna can transmit through it. This allows using several large antennas stacked over each other instead of several small antennas placed next to each other. This results in better sensitivity and directivity.

4. When a plasma element is not energised it is difficult to detect it by radar. Even when it is energised, it is transparent to the transmissions above the plasma frequency, which falls in the microwave region.

5. Plasma elements can be energised and de-energised in seconds, which prevents signal degradation.

6. When a particular plasma element is not energised, its radiation does not affect nearby elements.

 7. Plasma antenna can focus high- frequency radio waves that would dissipate quickly if beamed by conventional arrays.

8. Plasma antennas boost wireless speeds. Such antennas could enable next-generation Wi-Fi that allows for super-fast wireless data transfers.

9. Solid-state plasma antennas deliver gigabit-bandwidth, and high- frequency plasma antenna could hold the key for economically viable super- fast wireless networking.

10. Plasma antennas might also be used to create low-cost radar arrays that could be mounted on cars to help them navigate in low-visibility conditions, or used to make directed, more focused and less bulky energy weapons.

11. Plasma antennas have developed an innovative range of selectable multi-beam antennas that meet the demands in today’s wireless communication, defense and homeland security markets.
