Google Books is not just a digital catalog; it is a powerful research tool. Here’s why engineers prefer accessing Prasad’s work this way:
Use the search bar inside Google Books to query terms from your syllabus: “VSWR”, “Binomial array”, “Tropospheric scatter”. Note the page ranges.
The full title is often "Antenna and Wave Propagation" (Satya Prakashan), and it runs approximately 600-700 pages depending on the edition. Let’s break down the core sections that students search for on Google Books.
Before analyzing the book, it is crucial to understand the author. K.D. Prasad is a revered figure in Indian technical education. He is not just an academic but a prolific author whose works on antennas, microwaves, and digital communication have shaped the curriculum of universities under AICTE, UGC, and various state technical universities.
Prasad’s writing style is unique: he breaks down complex vector calculus and electromagnetic field theories into digestible modules. Unlike foreign authors who assume high-level prerequisite knowledge, Prasad builds from the ground up, making his book ideal for self-study. His other titles, including "Principles of Digital Communication" and "Microwave Engineering," also enjoy high demand, but "Antenna and Wave Propagation" remains his magnum opus.
Author: Dr. K.D. Prasad Primary Publisher: Satya Prakashan (New Delhi) Subject: Electronics & Communication Engineering Target Audience: B.Tech/B.E. students (Indian Universities), GATE/IES aspirants.
While searching Google Books, you may encounter links to third-party PDF repositories. Downloading pirated copies is illegal and harms authors like K.D. Prasad (whose royalties support ongoing academic work). More importantly, these PDFs are often:
Legitimate options:
At the end of each chapter, Prasad lists older ITU recommendations and IEEE papers. Copy those titles from Google Books and search IEEE Xplore for deeper dives.

ANTENNA AND WAVE PROPAGATION
It was a typical humid afternoon in the third-year engineering hostel at the Institute of Technology. The ceiling fan whirred overhead, struggling to cut through the tension that hung heavy in Room 304. antenna and wave propagation by kd prasad google books
Rahul sat hunched over his study table, his head in his hands. Spread out before him were messy handwritten notes and a printed syllabus for the upcoming semester exam. The subject: Antenna and Wave Propagation.
"I don't get it," Rahul groaned, running a hand through his hair. "I understand the basics, but when they ask about the 'Radiation Resistance of a Half-Wave Dipole' or the 'Friss Transmission Formula,' my mind goes blank. The professor's notes look like hieroglyphics."
Vikram, his roommate and the designated "topper" of the group, was leisurely sipping tea on the upper bunk. He peeked down, adjusting his glasses.
"You’re reading the notes?" Vikram asked, raising an eyebrow. "Notes are for last-minute cramming. If you want to actually understand the physics—and more importantly, pass K.D. Prasad’s territory—you need the source."
Rahul looked up, confused. "The source?"
Vikram hopped down from the bunk and walked over to his bookshelf. It was a sacred space, filled with thick, spine-broken tomes. He reached in and pulled out a hefty hardcover book. The cover was slightly faded, bearing the distinct, no-nonsense font of a classic technical publisher.
He slammed it onto Rahul’s desk. The sound was heavy, like a judge’s gavel.
"Antenna and Wave Propagation" by K.D. Prasad.
"This isn't just a book, Rahul," Vikram said solemnly. "This is the bible for this subject. And since the library copies are always checked out by the toppers, we do what every desperate engineer does at 2:00 AM."
"We buy it?" Rahul asked innocently.
Vikram scoffed. "No. We log in. Behold, the power of Google Books." Google Books is not just a digital catalog;
Vikram pulled up a chair and opened his laptop. He navigated to the Google Books website, typing the author's name with practiced speed. Within seconds, the digital card catalog appeared. There it was: Antenna and Wave Propagation by K.D. Prasad.
"See," Vikram pointed at the screen. "The beauty of K.D. Prasad isn't just the content, it's the structure. He starts with the fundamentals—Maxwell’s equations—and builds the antenna theory brick by brick. You don't need to memorize the radiation pattern of a Yagi-Uda antenna; you need to visualize it."
Rahul looked at the screen skeptically. "Is this a preview? I can't see the whole book."
"That’s the game," Vikram grinned. "Google Books gives you enough to save your life. You can usually access the index and critical chapters. Look here."
He clicked on the table of contents.
"The problem you're having," Vikram explained, scrolling through the preview of Chapter 2, "is that you're trying to memorize field equations without understanding the Point Source approximation. K.D. Prasad explains this beautifully. Look at this diagram."
On the screen, rendered in the stark black-and-white lines typical of technical textbooks, was the radiation pattern of an isotropic radiator.
"Google Books lets you search within the book," Vikram said, typing rapidly. "Let's fix your issue with 'Radiation Resistance'. He typed the phrase into the search bar. The results popped up, highlighting pages 173 and 174.
"It's a preview," Vikram admitted, "but look. You can see the derivation. He doesn’t just give you the formula $R_r = 73 \Omega$ for a half-wave dipole. He walks you through the Poynting vector integration."
Rahul leaned in. For the first time in weeks, the fog began to lift. The text on the screen was dense, academic, and devoid of flashy colors, but it had a rhythm. It was authoritative.
"So," Rahul murmured, reading a snippet on the screen. "The radiation resistance is a hypothetical resistance that would dissipate the same amount of power as the antenna radiates." Author: Dr
"Exactly," Vikram nodded. "And look at the propagation section. In the physical book, you’d be flipping pages for ages. Here, if you want to know about 'Skip Distance' in the Ionosphere, you just search for 'Sky Wave Propagation'."
Rahul took control of the mouse. He scrolled through the section on Wave Propagation. He saw diagrams of the ionosphere layers—D, E, and F layers. He saw the explanation of how frequency affects critical angles. The Google Books interface was clean, allowing him to focus on the text without the distraction of ads or pop-ups found on sketchy PDF sites.
"I used to think I needed a tutor," Rahul said, his eyes scanning the derivation of the Friss formula. "But this... this explains it step-by-step."
"K.D. Prasad doesn't mess around," Vikram said, leaning back. "His explanations are standard for a reason. He treats the reader like an engineer, not a child. The math is rigorous, but if you follow the logic, it’s flawless. And with Google Books, you have a digital index that makes finding needle-in-a-haystack topics instantaneous."
Rahul spent the next three hours glued to the screen. He toggled between the preview pages and his notebook. He finally understood why a dish antenna had a parabolic shape (the geometric optics approach explained clearly in Chapter 9) and why the height of an antenna mattered for ground wave propagation.
As the sun set and the room grew dark, Rahul closed the laptop. He felt a strange sensation—confidence.
"You think they have the chapter on Antenna Measurements?" Rahul asked.
"Probably," Vikram smiled. "But for that, we might need to raid the library tomorrow. The preview is good, but the full book is a treasure."
Rahul looked at the stack of notes he had previously been crying over. He pushed them aside.
"No need," Rahul said, tapping the laptop. "I’ve got the logic down now. K.D. Prasad and Google Books just saved my semester."
And in Room 304, the terrifying subject of Antennas was finally tamed, one digital page at a time.
