Sayan Chatterjee gave a presentation on plasma antennas. A plasma antenna uses ionized gas enclosed in a tube as the conducting element rather than metal. It was first proposed in 1919 and offers advantages like enhanced bandwidth, higher efficiency, lower noise, improved reliability and a smaller size compared to traditional antennas. Potential applications include high speed digital communication, stealth technology, and transmission/modulation techniques. Future developments could include next-generation Wi-Fi allowing for very fast wireless data transfers.
