The 1980s and 1990s were not only a period in which many developing countries adopted a series of major economic policy reforms, but also an era in which all socialist countries undertook varying degrees of radical reforms in their Soviet-style central-planning economic management systems. This volume examines the performance of China's industrial reform and open-door policy during the period of 1980-1997 through conducting a case study on one of its Special Economic Zones (SEZs), Xiamen. It adopts an analytical approach - examining Xiamen's performance from the perspective of three important interactions: between the country's general economic reform policies and the Special Policy implemented in the SEZs; between the Xiamen SEZ and the vast Chinese hinterland; and between foreign (especially Taiwanese) direct investment and local industrial transformation.

This book presents a comprehensive insight into the design techniques for different types of CP antenna elements and arrays In this book, the authors address a broad range of topics on circularly polarized (CP) antennas. Firstly, it introduces to the reader basic principles, design techniques and characteristics of various types of CP antennas, such as CP patch antennas, CP helix antennas, quadrifilar helix antennas (QHA), printed quadrifilar helix antennas (PQHA), spiral antenna, CP slot antennas, CP dielectric resonator antennas, loop antennas, crossed dipoles, monopoles and CP horns. Advanced designs such as small-size CP antennas, broadband, wideband and ultra-wideband CP antennas are also discussed, as well as multi-band CP antennas and dual CP antennas. The design and analysis of different types of CP array antennas such as broadband CP patch arrays, dual-band CP arrays, CP printed slot arrays, single-band and multi-band CP reflectarrays, high-gain CP waveguide slot antennas, CP dielectric resonator antenna arrays, CP active arrays, millimetre-waveband CP arrays in LTCC, and CP arrays with electronically beam-switching or beam-steering capabilities are described in detail. Case studies are provided to illustrate the design and implementation of CP antennas in practical scenarios such as dual-band Global Navigation Satellite Systems (GNSS) receivers, satellite communication mobile terminals at the S-band, Radio Frequency Identification (RFID) readers at 2.4 GHz, and Ka-band high-speed satellite communication applications. It also includes the detailed designs for a wideband Logarithmic spiral antenna that can operate from 3.4-7.7 GHz. In addition, the book offers a detailed review of the recent developments of different types of CP antennas and arrays. <ul>
<li>Presents comprehensive discussions of design techniques for different types of CP antennas: small-size CP antennas, broadband CP antennas, multi-band CP antennas and CP arrays.</li> <li>Covers a wide range of antenna technologies such as microstrip antennas, helix, quadrifilar helix antenna, printed quadrifilar helix antenna, dielectric resonator antennas, printed slots, spiral antennas, monopoles, waveguide slot arrays, reflectarrays, active arrays, millimetre-wave arrays in LTCC, electronically beam-switching arrays and electronically beam-steerable arrays.</li> <li>Reviews recent developments in different types of CP antennas and arrays, reported by industries, researchers and academics worldwide.</li> <li>Includes numerous case studies to demonstrate how to design and implement different CP antennas in practical scenarios.</li> <li>Provides both an introduction for students in the field and an in-depth reference for antenna/RF engineers who work on the development of CP antennas.</li> </ul>
Circularly Polarized Antennas will be an invaluable guide for researchers in R&amp;D organizations; system engineers (antenna, telecom, space and satellite); postgraduates studying the subjects of antenna and propagation, electromagnetics, RF/microwave/millimetre-wave systems, satellite communications and so on; technical managers and professionals in the areas of antennas and propagation.

An authoritative guide to the latest developments for the design of low-cost smart antennas Traditional smart antenna systems are costly, consume great amounts of power and are bulky size. Low-cost Smart Antennas offers a guide to designing smart antenna systems that are low cost, low power, and compact in size and can be applied to satellite communications, radar and mobile communications. The authors — noted experts on the topic — provide introductions to the fundamental concepts of antennas, array antennas and smart antennas. The book fills a gap in the literature by presenting the design techniques of low-cost radio frequency (RF) smart antennas as well as approaches for implementing the hardware of the antenna and the beamforming network (BFN). A comprehensive and accessible book, Low-cost Smart Antennas not only presents an up-to-date review of the topic but includes illustrative case studies that contain in-depth explorations of the theory and technology of smart antennas. While other resources highlight the software (signal processing algorithms), this book is unique by focusing on the antenna hardware. This important book: <ul>
<li>Offers an introduction to the most recent developments of the design of low-cost smart antennas and their applications</li> <li>Presents a unique book that puts the focus on antenna hardware</li> <li>Includes a variety of case studies that clearly demonstrate the implementation of current design techniques</li> <li>Introduces both fundamental theories as well as more advanced topics</li> </ul>
Written for students and researchers and antenna engineers, Low-cost Smart Antennas explores the most recent advances in the field with an emphasis on antenna hardware.
