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.

This book is a practical engineering guide to microwave material measurements for both laboratory and manufacturing/field environments, including nondestructive inspection (NDI) and nondestructive evaluation (NDE). The book covers proven methods for characterizing materials at microwave frequencies, including both resonant and wide-bandwidth techniques, and gives you the necessary theory and equations for implementing these methods. You’ll understand how to invert dielectric and/or magnetic material properties from free space transmission and reflection, and how to measure traveling wave attenuation. You’ll also know how to measure dielectric and/or magnetic material properties from transmission line fixtures, and learn how to use computational electromagnetic modeling with a measurement fixture.
