Book Synopsis Compact Antennas for Wireless Communications and Terminals by : Jean-Marc Laheurte
Download or read book Compact Antennas for Wireless Communications and Terminals written by Jean-Marc Laheurte. This book was released on 2012-12-27. Available in PDF, EPUB and Kindle. Book excerpt: Compact Antennas for Wireless Communications and Terminals deals with compact microwave antennas and, more specifically, with the planar version of these antennas. Planar antennas are the most appropriate type of antenna in modern communication systems and more generally in all applications requiring miniaturization, integration and conformation such as in mobile phone handsets. The book is suitable for students, engineers and scientists eager to understand the principles of planar and small antennas, their design and fabrication issues, and modern aspects such as UWB antennas, reconfigurable antennas and diversity issues.

Book Synopsis Design, Modeling, and Optimization of Compact Broadband and Multiband 3D System-On-Package (SOP) Antenna Architectures for Wireless Communications and Millimeter-wave Applications by : Gerald Reuben DeJean
Download or read book Design, Modeling, and Optimization of Compact Broadband and Multiband 3D System-On-Package (SOP) Antenna Architectures for Wireless Communications and Millimeter-wave Applications written by Gerald Reuben DeJean. This book was released on 2007. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the miniaturization of cell phones and computers has led to a requirement for antennas to be small and lightweight. Antennas, desired to operate in the WLAN frequency range, often possess physical sizes that are too large for integration with radio-frequency (RF) devices. When integrating antennas into three-dimensional (3D) system-on-package (SOP) transceivers, the maintenance of a compact size also provides isolation from other devices, hence, surface wave propagation or high dielectric constant materials such as low temperature cofired ceramics (LTCC) does not affect nearby components of the transceiver such as filters, baluns, and other embedded passives. Therefore, the application of design methods is necessary for realizing compact antennas in the wireless community that can be integrated to RF packages. Furthermore, it is essential that these compact antennas maintain acceptable performance characteristics, such as impedance bandwidth, low cross-polarization, and high efficiency. In addition, the analysis of circuit modeling techniques that could be used to obtain a better understanding of the physical phenomena of the antenna is quite necessary as modules become more and more complex. Based on these requirements, the focus of this research is to improve the design of compact antennas for wireless communications, wireless local area networks (WLAN), and millimeter-wave applications by using time-domain electromagnetic and circuit modeling techniques and optimizations. These compact antenna designs are applied to practical wireless communications systems such as global system of mobile communications (GSM), Bluetooth Industrial-Scientific-Medical (ISM) devices, IEEE802.11a WLAN, and Local Multipoint Distribution Systems (LMDS) applications. Parametric analyses are conducted to study critical parameters that may affect the antenna designs. Moreover, optimizations are performed to optimize the structures, and measured results are presented to validate design techniques.

Book Synopsis Compact Multifunctional Antennas for Wireless Systems by : Eng Hock Lim
Download or read book Compact Multifunctional Antennas for Wireless Systems written by Eng Hock Lim. This book was released on 2012-04-17. Available in PDF, EPUB and Kindle. Book excerpt: Offers an up-to-date description of modern multifunctional antenna systems and microwave components Compact multifunctional antennas are of great interest in the field of antennas and wireless communication systems, but there are few, if any, books available that fully explore the multifunctional concept. Divided into six chapters, Compact Multifunctional Antennas for Wireless Systems encompasses both the active and passive multifunctional antennas and components for microwave systems. It provides a systematic, valuable reference for antenna/microwave researchers and designers. Beginning with such novel passive components as antenna filters, antenna packaging covers, and balun filters, the book discusses various miniaturization techniques for the multifunctional antenna systems. In addition to amplifying and oscillating antennas, the book also covers design considerations for frequency- and pattern-reconfigurable antennas. The last chapter is dedicated to the field of solar cell integrated antennas. Inside, readers will find comprehensive chapters on: Compact Multifunctional Antennas in Microwave Wireless Systems Multifunctional Passive Integrated Antennas and Components Reconfigurable Antennas Receiving Amplifying Antennas Oscillating Antennas Solar cell integrated Antennas Aimed at professional engineers and researchers designing compact antennas for wireless applications, Compact Multifunctional Antennas for Wireless Systems will prove to be an invaluable tool.
