A comprehensive introduction to the theory and practice of differential antennas The first antennas ever created were differential antennas, in the dipole and loop constructions, before the subsequent creation of the single-ended or monopole antenna. Dozens of antenna configurations have been invented since then, the vast bulk of them differential. The theory and design of differential antennas therefore has an impact on a huge range of fields which make use of electromagnetic waves, radar arrays, and more. Differential Antennas contains a thorough, comprehensive overview of these antennas, their theory, and their practical applications. It details the relationship between differential and single-ended antennas, which may act as tools for determining the properties of one when the other is known. This book offers an analysis of the role differential antennas play in wireless communication and sensing. Overall, it stands as an essential contribution to a key area of communications technology. Differential Antennas readers will also find: Tables and figures illustrating key data, antenna structures, and more Chapters covering topics including microstrip antennas, shorted patch antennas, grid array antennas, and other designs Detailed instructions for measuring antennas for characterization and specification purposes Differential Antennas is ideal for senior and graduate level students, researchers, and radio frequency engineers.
