Накратко на български

Плазмените антени използват йонизиран газ в тръби за изпращане и приемане на радиовълни, вместо традиционен метал. Тази технология позволява бърза електрическа промяна на честотата и посоката на сигнала, което подобрява гъвкавостта и работата на антенните системи.

Plasma Antenna Technologies

High density plasma sources find a large number of industrial applications from material treatment to telecommunications. Overcoming the plasma density limit of a current source will open new frontiers in several technological fields. PATH aimed at cross linking different competences to study and develop prototypes of plasma sources and plasma antennas based on radiofrequency (RF), direct current (DC) Hollow cathode, and hybrid technologies to be applied in gaseous plasma antennas (GPAs). A GPA is a plasma discharge confined in a dielectric tube that uses partially or fully ionized gas to generate and receive electromagnetic waves; GPAs are virtually “transparent” above the plasma frequency and become “invisible” when turned off. Unlike ordinary metallic antennas, GPAs and plasma antenna arrays can be reconfigured electrically (rather than mechanically) with respect to impedance, frequency, bandwidth, and directivity on time scales in the order of microseconds or milliseconds. It is also possible to stack arrays of GPAs designed to operate at different frequencies, as the mutual coupling between different GPA can be greatly reduced with respect to the one of conventional antennas. During the project, an ultra-high frequency (UHF) dipole based on RF plasma technology has been developed and tested. The performance of this radiating element has been investigated via numerical analysis and tests and compared with a conventional dipole. A small array of plasma dipoles was numerically simulated to demonstrate that the mutual coupling between such elements is better than the one exhibited by conventional antenna arrays. This would suggest that this novel technology should improve the antenna system performance when flexibility and reconfigurability are the driving requirements. This new technology of antennas based on plasma is well suited to applications in intelligent antenna systems, where ad hoc algorithms can exploit the capabilities of plasma antennas to tailor to the user needs within certain limits with sensible cost savings.

Цел на проекта

PATH is intended to promote a collaborative researches focused in the development of high density plasma sourcesimplemented with the Exchange of staff personnel between the partners of the network. The research will also addresstransfer of knowledge and training of the researchers in the specific field of plasma sources and its applications in the telecommunication sector.High density plasma sources find large number of industrial applications from material treatment to Telecommunication.

It is also possible to stack arrays of GPAs designed to operate at different frequencies. A Plasma Antenna will be able to: (i) identifying the direction of incoming signal, (ii) tracking and locating the antenna beam on the mobile/target, (iii) beam-steering while minimizing interferences.Actual technology is based mainly on: (i) DC discharge, (ii) AC discharge, (iii) RF discharge, (iv) Microwaves, (v) Hollow cathode. Improvement of plasma source performances require a strong effort in term of modelling and technology. The aim of PATH is to merge European competences to make a substantial step toward innovative hybrid plasma sources.
