The third editionof Antenna Theory is designed to meet the needs of electrical engineering and physics students at the senior undergraduate and beginning graduate levels, and those of practicing engineers.
This book provides some recent advances in design nanometer VLSI chips. The selected topics try to present some open problems and challenges with important topics ranging from design tools, new post-silicon devices, GPU-based parallel computing, emerging 3D integration, and antenna design.
An ultrawideband (UWB) pentagon shape planar
microstrip slot antenna is presented that can find applications
in wireless communications. Combination of the pentagon shape
slot, feed line and pentagon stub are used to obtain 124%
(2.65–11.30 GHz) impedance bandwidth which exceeds the UWB
requirement of 110% (3.10–10.60 GHz). A ground plane of 50 mm
80 mm size is used which is similar to wireless cards for several
portable wireless communication devices. The proposed antenna
covers only the top 20 mm or 25% of the ground plane length,
which leaves enough space for the RF circuitry.
Mobile and wireless communications applications have clear impact on improving the
humanity wellbeing. From cell phones to wireless internet to home and office devices, most of
the applications are converted from wired into wireless communication. Smart and advanced
wireless communication environments represent the future technology and evolutionary
development step in home, hospitals, industrial, and vehicular and transportation systems.
As the growing demand formobile communications is constantly increasing, the need for better
coverage, improved capacity and higher transmission quality rises. Thus, a more efficient use
of the radio spectrum is required. Smart antenna systems are capable of efficiently utilizing the
radio spectrum and, thus, is a promise for an effective solution to the present wireless systems’
problems while achieving reliable and robust high-speed high-data-rate transmission. The
purpose of this book is to provide the reader a broad viewof the systemaspects of smart antennas.
dipole antenna is a radio antenna that can be made of a simple wire, with a center-fed
driven element. It consists of two metal conductors of rod or wire, oriented parallel and
collinear with each other (in line with each other), with a small space between them. The
radio frequency voltage is applied to the antenna at the center, between the two
conductors. These antennas are the simplest practical antennas from a theoretical point of
The book addresses practical engineering issues that antenna professionals have to deal with. It explains the immediate demands for existing systems; discusses the antenna technology for the latest and emerging applications, and gives comprehensive coverage of hot topics in the wireless industry. Issues including design considerations, engineering design, measurement setup and methodology, and practical applications are all covered in depth.
Most antenna engineers are likely to believe that antennas are one technology that is more or less impervious to the rapidly advancing semiconductor industry. However, as demonstrated in this lecture, there is a way to incorporate active components into an antenna and transform it into a new kind of radiating structure that can take advantage of the latest advances in analog circuit design
The research, simulation and design dual band antenna which operates at 900MHz and 2.45GHz are conducted. FR4-epoxy substrate is chosen with thickness h = 1.5mm, εr = 4.4. Dual band can be achieved by using different methods of impedance’s matching for single antenna which is originally designed at 900MHz. Some dual band RFID structures are discussed in this paper.

The Topic of microstrip antennas is an old subject that started over 40 years ago. Microstrip
antennas are low profile and easily fabricated. This subject has passed through several
stages that make it survive tell now and still in continues progress. The main stage is the
development of low loss low cost dielectric materials that make it possible to design an effi‐
cient low profile microstrip patches. The stage of developing analysis methods and models
that helped in the design of radiating...
