Topic: Metamaterial-inspired Design of Efficient Electrically Small Antennas (May to July, 2010)
Supervisor: Prof. Kumar Vaibhav Srivastava (Electrical Engineering Department, IIT Kanpur)
Abstract: Design of efficient miniaturized antennas is a problem of utmost importance for its stringent needs in the field of communication technology and sensor networks. Such electrically small antennas (ESAs) are inherently inefficient narrowband radiators. Several classical techniques have been proposed in the past for improvement in their radiated power, bandwidth and directivity, for obtaining an optimised antenna system suitable for practical fabrication. But these techniques mostly fail to keep the system electrically small. After the practical realization of artificially engineered metamaterials in the 21st century, researchers have resorted to some novel techniques for efficiently addressing the issue of trade-off between miniaturization and improvement in antenna performance, by using metamaterial-paradigm in antennas.
In this work, some metamaterial-inspired design methodology of electrically small antenna systems have been theoretically studied and simulated. Some improvised structures have also been proposed. The simulated results clearly show that use of metamaterial-inspired structures increase the radiated power of dipole and monopole antennas in some cases, whereas the system still remains narrowband. On the other hand, the antenna bandwidth becomes significantly large for some designs, along with considerable minimization of overall antenna systems.
1. Analysis of Planar Microstrip Circuits Using FDTD method
Guided by: Prof. Dipak Ranjan Poddar (Jadavpur University) and Prof. Rowdra Ghatak (NIT, Durgapur)
Summary of work: Developed conditionally stable FDTD code in MATLAB platform for analysis of microstrip circuits (transmission lines, filters, branch-line couplers), as well as microstrip patch antennas. Also the FDTD code was extended for the analysis of dispersive metamaterials having negative permittivity and / or negative permeability characteristics.
2. Studies on Nonlinear Dynamics in RF and Microwave Oscillator Systems
Guided by: Prof. Bishnu Charan Sarkar (Burdwan University) and Prof. Suvra Sarkar (Burdwan Raj College)
Summary of work: Contributed in building MATLAB codes for analysis of nonlinear dynamical properties of single as well as coupled oscillator systems (eg. Gunn, Colpitts). The main focus was on observation of bifurcation and chaotic states for choice of different design parameters.
