Microwave Material Applications: Device Miniaturization and Integration by David B. Cruickshank Pdf

This comprehensive new resource based on the classic Artech House title, Microwave Materials for Wireless Applications, introduces the use of new microwave materials for passive devices including ferrites, magnetization garnets, dielectric materials, and absorbers for wireless and antenna applications. This book explores a new set of magnetic and dielectric materials that assist with size reduction of passive devices such as ferrite isolators and circulators. Revised data on the applications of absorbers, including examples of different combinations of magnetic, dielectric, and absorber materials into integrated devices is presented. Meta-materials for antennas and potential antenna integration onto soft boards or LTCC filter technologies using tunable devices with new materials are covered. Professionals learn how new material designs use properties of certain ions in oxide compounds to reduce their physical size, including in cellular base stations designed for 4G and 5G cell phone communication systems. This book exhibits how the integration of new materials into cellular systems using common transmission lines will further save size and reduce complexity. New technologies are presented demonstrating the use of sol-gel processing and ceramic processing in the use of low temperature co-fired ceramics, plastic molding, and 3D printing demonstrating improved device designs.

Tunable Microwave Metamaterial Structures by Matthias Maasch Pdf

This book presents original findings on tunable microwave metamaterial structures, and describes the theoretical and practical issues involved in the design of metamaterial devices. Special emphasis is given to tunable elements and their advantages in terms of feeding network simplification. Different biasing schemes and feeding network topologies are presented, together with extensive prototype measurements and simulations. The book describes a novel, unique solution for beam steering and beam forming applications, and thus paves the way for the diffusion of new agile communication system components. At the same time, it provides readers with an outstanding and timely review of wave propagation in periodic structures, tunability of metamaterials and the technological constraints that need to be considered in the design of reconfigurable microwave components.

Ferroelectrics in Microwave Devices, Circuits and Systems by Spartak Gevorgian Pdf

Today’s wireless communications and information systems are heavily based on microwave technology. Current trends indicate that in the future along with - crowaves, the millimeter wave and Terahertz technologies will be used to meet the growing bandwidth and overall performance requirements. Moreover, motivated by the needs of the society, new industry sectors are gaining ground; such as wi- less sensor networks, safety and security systems, automotive, medical, envir- mental/food monitoring, radio tags etc. Furthermore, the progress and the pr- lems in the modern society indicate that in the future these systems have to be more user/consumer friendly, i. e. adaptable, reconfigurable and cost effective. The mobile phone is a typical example which today is much more than just a phone; it includes a range of new functionalities such as Internet, GPS, TV, etc. To handle, in a cost effective way, all available and new future standards, the growing n- ber of the channels and bandwidth both the mobile handsets and the associated systems have to be agile (adaptable/reconfigurable). The complex societal needs have initiated considerable activities in the field of cognitive and software defined radios and triggered extensive research in adequate components and technology platforms. To meet the stringent requirements of these systems, especially in ag- ity and cost, new components with enhanced performances and new functionalities are needed. In this sense the components based on ferroelectrics have greater - tential and already are gaining ground.
