Dielectric Resonator Antenna (DRA) is a ground-breaking innovation in antenna engineering that emerged 40 years ago in 1983. This antenna design revolutionized the field by utilizing ceramic materials exclusively as the radiating unit, presenting a significant departure from traditional antenna construction. Initially, DRA faced challenges due to the availability of suitable dielectric materials and the difficulties in machining them for shaping the antenna units. However, over the past four decades, DRA has demonstrated its potential and evolved into a viable alternative to low-profile printed antennas.
One of the key objectives of this project is to explore novel ideas, features, and various contemporary and future applications of DRA. For instance, satellite-to-satellite communication in the millimetre-wave range is a significant application where DRA technology can prove invaluable. With 5G systems demanding robust and efficient antenna systems, DRA can play a vital role in meeting these requirements. Additionally, biomedical sensors and antenna-embedded sensors are emerging areas where DRA innovations can greatly contribute. Therefore, DRA technology is poised to lead in multiple industries and applications.
