Author Description

Antenna designers are facing problem of widening bandwidth, and improving gain, in addition to miniaturization and optimization of radiation properties. Many existing wireless applications and radar applications operate over wideband frequency bands and, thus require broad band antenna. The motivation for this work has been inspired by identifying the issues subjected to the design of DRAs and the need for compact, highly efficient and low cost antenna. These antennas are also suitable for quality wideband operation with the possibilities of compatibility with microwave integrated circuits, (MICs). In order to achieve research goals, the focus in this book is on the investigation of DRA properties as well as the design and analysis of various antenna configurations exhibiting enhanced performances. The smartness of RDRA will be obtained by variation of parameter like Permittivity and loss tangent. Chapter 2 has a review and Chapter 3 includes the mathematical modeling of design of rectangular and cylindrical DRA. Chapter 4 includes the simulation technique and analysis of different design shape of DRA. Chapter 5 has mainly focus on conclusion, highlights and future scope of work.
