Antenna Systems for Modern Wireless Devices (Signals and Communication Technology)
by Shiban K. Koul S. Swapna G. S. KarthikeyaThis book presents up-to-date information about WLAN antenna designs for students, researchers, and professionals who want to design radiating systems to be deployed for practical coverage. The book primarily focuses on pattern diversity antennas. Pattern diversity antennas are very vital in wireless communication. High correlation between multiple signals can result in low data throughput which can be solved by using antennas with pattern diversity. Beam scanning antennas and their variants are also described in detail. Pattern diversity antenna systems with multiport feeds are also comprehensively discussed in this book. For a multiport system to maintain a reasonable link budget, equal antenna gains are preferred for the required antenna coverage. The book further describes the latest techniques to enhance and equalize the antenna gain within a compact radiating system. With increasing demand for faster connectivity with minimum path loss, the demand for high-gain antennas is rapidly increasing. Thereby a detailed discussion on gain enhancement with the latest high-gain antenna designs is requisite while describing WLAN antennas. Some antenna designs discussed in the book are based on additive manufacturing for their design and fabrication. Additive manufacturing is a much sought-after technology today that allows rapid development of antennas at an affordable cost. Many recent WLAN antennas make use of this technology to develop versatile antenna designs. Finally, the book includes a section on wide-band antenna designs. Antenna designs that reduce the scanning loss are also discussed.

Antennas: Rigorous Methods of Analysis and Synthesis
by Boris LevinThe book comprises a new method of solving the integral equation of Leontovich, the most rigorous and most effective equation for the current in thin linear antennas. The book describes the features of the new method in its application in various types of antennas. It considers new ways of analyzing antennas, in particular in the calculation of an antenna gain based on main radiation patterns and the calculation of the directional characteristics of radiators with known distribution of current amplitude. The method of electrostatic analogy proposed by the author, provides the base for comparison of electromagnetic fields of high-frequency currents and electrostatic charges located on linear conductors to improve the directional characteristics of log-periodic and director-type antennas. A new approach to the analysis of the electrical characteristics of a microstrip antenna, which allows expansion of its operation range, is substantiated and developed. New results of antenna synthesis are obtained. The second part of the book is devoted to specific types of antennas (the author had a significant role in their creation). Particular attention is given to ship antennas for different frequency ranges. The book is intended for professionals, working in electrodynamics and those working on development, placement and exploitation of antennas. It will be useful for lecturers (university-level professors), teachers, students of radio engineering and researchers working in various fields of radio electronics and interested in an in-depth study of theoretical problems and designs f antennas. It can also be used for short university courses.
Antennas: From the Theory of Long Lines to Integral Equations
by Boris LevinThis book describes both known and new results. In the sections devoted to the use of integral equations for the current in a linear metal radiator, the focus is on Leontovich's equation. An advantage of this equation is the simplicity of the solution and the absence of the argument φ in it because the integration over φ already performed. The refined solution makes it possible to determine the total sum of the series for the current, which is close to the known solution including only the first terms. The results of the synthesis of different types of antennas with capacitive loads are presented, which makes it possible to implement Hallen's hypothesis about the usefulness of applying such loads to create an in-phase current distribution in antennas and to obtain required characteristics.New results include the widespread use of the complex potential method in relation to the calculation of capacitive structures in homogeneous and inhomogeneous media, antenna patterns and flows of electrical fields between antenna elements and in the surrounding space. In particular, the analysis of field flows makes it possible to substantiate a rigorous method for analyzing microstrip antennas. The characteristics of antennas in various conditions of their installation are considered and compared. The results of the use of multi-floors structures that provide in the wide frequency range the radiation in direction perpendicular to the antenna axis, and structures that make it possible to reduce the mutual influence of antennas located at different heights on a common mast are described.

The Anterior-Based Muscle-Sparing Approach to Total Hip Arthroplasty
by Jeffrey A. Geller Brian J. McGroryThe minimally invasive, anterior-based muscle-sparing (ABMS) approach to total hip arthroplasty (THA) is utilized worldwide in select locations as an effective surgical technique. As the name suggests, it is completely muscle-sparing and touts the benefits of anterior-based surgery, including a lower dislocation rate, quicker return to baseline function, and lower narcotic use than many other surgical approaches. However, there is a paucity of collected information on the technique and research associated with this technique.This text serves as a compendium of information for those surgeons interested in utilizing this surgical approach as an all-inclusive reference. As an alternative anterior-based approach to the direct anterior surgical approach, some surgeons may find the technique an improved alternative for anterior hip-based surgery. Opening chapters present the history of the anterolateral approach and how to transition to the ABMS approach, including surgical anatomy. ABMS technique with the patient positioned in both the lateral and supine positions are then presented, including associated video segments. Considerations such as implant selection, fixation, and other tips and tricks are shared, along with comparisons to other approaches, patient-reported outcomes, complications and revision surgery techniques, and rehabilitation strategies.For hip surgeons looking to expand their armamentarium of surgical approaches, The Anterior-Based Muscle-Sparing Approach to Total Hip Arthroplasty is a terrific resource.
