The syllabus for Antenna and Wave Propagation covers a broad range of topics, forming the cornerstone of modern wireless communication systems.
Consists of a direct ray and a ground-reflected ray traveling through the troposphere. Operates primarily at frequencies above (VHF, UHF, and Microwaves). Consists of a direct ray and a ground-reflected

By studying antennas and wave propagation, engineers can design efficient communication systems that can transmit and receive signals reliably over long distances. The knowledge gained from this subject is essential for developing various communication systems, including radio communication systems, satellite communication systems, and wireless networks.

When building or studying a PPT slideshow for this subject, structure the presentation sequentially: align your slides directly with the analytical derivations provided in the text. Start with the foundational vector calculus and Maxwell's field equations, transition into individual antenna elements, expand to array configurations, and conclude with real-world wave propagation environments.
Waves glide along the curvature of the Earth's surface.
This is the "bread and butter" of K.D. Prasad’s book, covering:
