Terahertz Antennas: Catalyst for Ultra-Low Latency and unprecedented data rates in 6G communication

The imminent arrival of sixth-generation (6G) wireless communication networks promises a paradigm shift in connectivity, characterized by unprecedented data rates, ultra-low latency, and massive device connectivity. This transformation is fuelled by the ever-increasing demand for bandwidth-intensive applications and the proliferation of smart devices, necessitating a move beyond the limitations of current 5G infrastructure. The exploration of higher frequency bands, particularly the terahertz spectrum, is pivotal to realizing the ambitious goals of 6G, with THz antennas emerging as a critical enabling technology. As 5G technology is implemented across the globe, experts are already looking forward to 6G networks, which will integrate sensing, communication, computing, and control operations. It is envisioned that 6G will be a fully autonomous, decentralized, multi-band, user-centric, and hyper-flexible system. Terahertz communications will be an integral part of the 6G ecosystem, and thus it is expected to open new possibilities in several applications.

Terahertz antennas, operating in the frequency range of 0.1 to 10 THz, offer the potential to unlock vast swaths of unused bandwidth, enabling data transmission rates far exceeding those achievable with existing microwave and millimetre-wave technologies. However, the unique characteristics of THz waves, such as high atmospheric absorption and significant propagation losses, pose significant challenges to antenna design and system integration.

This emerging field of Terahertz antennas will open up many avenues in job market for Electronics and Communication Engineers. The research and development in the area of metasurface based Terahertz antennas has picked up enormous pace. Bengaluru, the tech capital of India has particularly been watchful and keeping pace with this evolving generation of technology.

The rising demand of antenna and RF engineers is surely going to put world class B. Tech Programmes in Electronics and Communication Engineering and VLSI Engineering back in demand. Presidency University situated in Bangalore, with its locational advantage, is a blooming ground for such ground-breaking disciplines of engineering ready to cater to the increased demand of world-class Engineers.
