Core Topics Covered in KD Prasad (Antenna and Wave Propagation)

How well an antenna concentrates power.

Clear, hand-drawn and digital vector diagrams illustrate radiation spheres, wave vectors, and structural dimensions of antennas.

"Antennas and Wave Propagation" by K.D. Prasad is a foundational textbook for electronics, telecommunications, and electrical engineering students. It bridges the gap between abstract electromagnetic theory and practical radio frequency (RF) engineering.

Introduction to antenna terminology, static electric and magnetic fields, and electromagnetic radiations.
