Plasma Antenna

INTRODUCTION WHAT IS PLASMA ?-An ordinary matter found by Sir William Crookes

a fourth state of matter, now known as

plasma. - Plasmas are conductive assemblies of charged

and neutral particles.- Plasmas carry electrical currents and generate

magnetic fields.- Types of Plasma are:- Warm Plasma Cold Plasma-Cold Plasma is used for antenna applications.

PLASMA ANTENNA TECHNOLOGY - Operates up to 90 GHz.

- It use ionized gas as counducting material .

- The gas is ionized only for the time of transmission or reception.

-The design allows for extremely short pulses, important to many forms of digital communication and radars.

-Predicted performance:- Beam Positions= 16 Gain= 14dB Switching speed= 2 micro sec

- Low weight and smaller in size 2

UNIQUE FEATURE OF PLASMA ANTENNA

One fundamental distinguishing feature of a plasma antenna is that the gas ionizing process.

A second fundamental distinguishing feature is that after sending a pulse the plasma antenna can be deionized.

Selectable Multi beam.3

SelectaBeam

Key Features of Slectabeam:-

Based on Beam forming tecnology. Avoid the need of alignment and realignment of

fixed point to point links. Same Benifites as that of Phased array antenna.

ReflectaBeam

Key Features of Reflectabeam:-

Operates upto Freqencies of 90Ghz Design to provide high speed selection At High Fequencies Applications it also

include radar sensors and monitering systems

Advantages of Selectabeam and Reflectabeam

High directional gain: concentrates RF power to increase link budget, dramatically enhancing network coverage and capacity.

Low sidelobes reduce interference, enabling improved frequency re-use and substantially higher utilization.

Wide bandwidth supports simultaneous multi-band or UWB operation from a single compact antenna.

High speed beam switching enables spatial time division multiplexing to boost spectral efficiency and throughput.

Compact and lightweight form factor reduces site and mast costs, simplifies installation and minimizes environmental impact.

Maintenance free - auto-aligning with no moving parts and requires no calibration, minimizing total cost.

PSiAn • Plasma antenna up coming Technology is

PSiAn Launched in 2010• Based on silicon integrated circuits

technology• Its product cost does not increase with

frequency• Frequncy range -1 to 300GHzAdvantages:-• Wide band Multimedia• Wireless local networks• Medical etc

TRADITIONAL ANTENNA VS PLASMA ANTENNA

-Unlike simple directional antennas, Plasma Antennas’ selecta-beam avoiding the need for manual or mechanical alignment and realignment of fixed point-to-point communication links. 

-Plasma Antennas’ selectable-beam antennas provide similar advantages to phased array antennas but at a fraction of the cost, together with much wider bandwidth of operation.
