QIP Short Term Course on Efficient and Low-Loss Antenna Configurations 2018
The requirement for efficient and low-profile antennas has fuelled research work in the development of antenna structures with performances considerably enhanced over traditional antenna structures and methodologies. In this context, the development of the dielectric resonator antenna technology has taken significant strides in overcoming fundamental limitations in the design of broadband and efficient antenna structures. On the other hand, metamaterials have played a significant and dominant role in size reduction and performance enhancement of microwave devices including both antennas and guided wave components. The dielectric resonator antenna is ideally suited for low-loss applications due to the absence of conductors or surface-wave loss. Furthermore, the achievable bandwidth with the dielectric resonator topology of the order of 60% or more with absolute stability of radiation characteristics across the entire impedance bandwidth far exceeds that of broadband microstrip patch antenna configurations. However, in spite of the potential of the dielectric resonator technology, analysis techniques for the dielectric resonator antenna have not received adequate attention particularly in the Indian context. This is particularly also significant as the analysis leads us to the in depth understanding of the modes of the antenna structure and their contribution to the dielectric resonator coupling problem. In addition, current research on microwave techniques and applications increasingly focus on novel and engineered materials to fulfill the stringent needs of modern communication. In this context, though the concept of opposing phase and group velocities in a periodic structure has been known to the microwave community, the application of the technology to the design of novel microwave devices has been relatively recent. Particularly, the metamaterial technology has been used to revisit traditional limits in the design of guided structures and antenna systems. The course would thus also focus on a comprehensive treatment of the metamaterial technology and design in the realization of efficient guided wave and antenna systems.
