Kumar, VikramGupta, Dileep Kumar2025-01-272025-01-272022978-012823457-0; 978-012823594-2https://dl.bhu.ac.in/ir/handle/123456789/14660This chapter discusses the essential components of microwave systems, which are relevant for designing a microwave radar measurement setup. The ways in which transmission lines are used in planar and waveguides lead to requirement for other components in planar or waveguide-based design. With a discussion on some primary antennas, the chapter reviews microwave absorbers and their characteristics. The power dissipation equation is established regarding the absorbing material. A few important microwave sources are discussed. The need for a mode converter in a microwave system leads to the necessary modes obtained from source-generated modes. A network analyzer is also discussed, which has the ability to measure the reflection loss and transmission loss of microwave power. � 2022 Elsevier Inc.
