Microstrip and printed antennas: new trends, techniques and applications

Attention is given to fundamental concepts and techniques, their practical applications and the future scope of developments. Several topics, essayed as individual chapters include reconfigurable antenna, ultra-wideband (UWB) antenna, reflectarrays, antennas for RFID systems and also those for body area networks. Also included are antennas using metamaterials and defected ground structures (DGSs). Essential aspects including advanced design, analysis and optimization techniques based on the recent developments have also been addressed INDICE: Table of contents Chapter 1 Numerical Analysis Techniques Ramesh Garg, Indian Institute of Technology, Kharagpur, India 1.1 Standard (Yees) FDTDMethod 1.2 Numerical Dispersion of FDTD Algorithms and Hybrid Schemes 1.3 Stability of Algorithms 1.4 Absorbing Boundary Conditions 1.5 LOD-FDTD Algorithm 1.6 Robustness of Printed Patch Antennas 1.7 Thin Dielectric Approximation 1.8Modeling of PEC and PMC for Irregular Geometries Chapter 2 Computer Aided Design of Microstrip Antennas Debatosh Guha, Institute of Radio Physics and Electronics, University of Calcutta, India Jawad Y.
