i request you to send some project ideas based on plasma antenna..
thank you so much..for your quick reply i think this would help me further to move into the project

PLASMA ANTENNA INTRODUCTION Plasma Antenna is a special type of antenna in which the metal conducting elements of a conventional antenna are replaced by a plasma. PLASMA Fourth state of matter similar to gas. Sir William Crookes, an English Physicist identified it in 1879. According to Markland’s technology, plasmas are conductive assemblies of charged and neutral particles and fields that exhibit collective effects. GENERATION OF ELECTRIC AND MAGNETIC FIELD When voltage applied to an antenna,electric field produced. Causes current to flow in antenna. Due to current flow,magnetic field produced. These two fields are emitted from an antenna and propagate through space over very long distances. PLASMA ANTENNA TECHNOLOGY It employs an ionized gas enclosed in a tube as the conducting element of an antenna. When the gas is electrically charged or ionized to a plasma,it becomes conductive and allowing radio frequency signals to be transmitted or received. When gas is not ionized,the antenna element ceases to exit. WORKING PRINCIPLE When supply is given to the tube, the gas inside it gets ionised to plasma. When plasma is highly energised, it behaves as a conductor. Antenna generates a localised concentration of plasma to form a plasma mirror that deflects RF beam launched from a central feed located at focus of mirror. CONCLUSION It is more advantageous than other antenna due to ionized gas. Its action has many general with the dielectric antenna action. It helps in pulse operation. |
