K.D. Prasad’s writing style is distinctly academic and tailored to the syllabi of major Indian universities. Unlike some western reference books that dive deep into theoretical abstractions, Prasad focuses on problem-solving. The book is packed with solved numerical examples that are frequently asked in university exams.
This is often considered the most difficult topic for students. K.D. Prasad breaks down the structure of the Ionosphere, the mechanism of refraction, and the concept of the Maximum Usable Frequency (MUF). The derivation of the skip distance and the explanation of the fading phenomenon are exceptionally clear. k d prasad antenna and wave propagation pdf download
The book covers the entire spectrum of the subject, from the basics of radiation to advanced antenna systems. It bridges the gap between electromagnetic theory and practical antenna design, making it easier for students to visualize complex concepts. The book is packed with solved numerical examples
One of the strengths of this book is its treatment of Antenna Arrays. Students often struggle with the mathematics of the Array Factor. Prasad excels in explaining the pattern multiplication principle, broadside arrays, and end-fire arrays. The graphical representations of array patterns make it easier to visualize how adding elements changes the beamwidth and directivity. Prasad breaks down the structure of the Ionosphere,
The book explains how waves travel along the surface of the earth, detailing the effects of the earth’s curvature and conductivity. It includes vital calculations for field strength in ground wave propagation.
In the realm of electronics and communication engineering, few subjects are as pivotal—or as challenging—as Antenna and Wave Propagation. For students preparing for semester exams, GATE, or competitive engineering services, having the right resource is half the battle won. Among the most sought-after textbooks in this domain is the comprehensive work by K.D. Prasad.
