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.
