Low-Visibility Antennas for Communication Systems

Description

Low-visibility antennas have many attractive features, such as being low-profile, flexible, lightweight, small-volume, and low-cost. Low-Visibility Antennas for Communication Systems provides explicit guidelines for the development of these antennas. Offering valuable insight into emerging antenna technologies, the book:

• Introduces the fundamental theory of electromagnetics and antennas with few integral and differential equations, improving accessibility while providing sufficient mathematical detail
• Presents state-of-the-art advancements in microstrip, millimeter (mm) wave microstrip, wearable, wearable tunable printed, wideband wearable meta-material, and fractal printed antennas
• Discusses microwave integrated circuits (MICs), monolithic microwave integrated circuits (MMICs), micro-electro-mechanical systems (MEMS), and low temperature co-fired ceramics (LTCC)

Low-Visibility Antennas for Communication Systems delivers a comprehensive and cutting-edge study of the design and application of low-visibility antennas, complete with design considerations, computed and measured results, and an extensive exploration of radio frequency and antenna measurements.
