Antennas and Wave Propagation K.D. Prasad , published by Satya Prakashan

Step 3: Create a "Propagation Cheat Sheet"

The wave propagation half of the book is definition-heavy. Using your PDF, extract the following into a one-page table: | Mode | Frequency range | Distance | Application | Limitation | | :--- | :--- | :--- | :--- | :--- | | Ground wave | LF/MF (30 kHz–3 MHz) | 100–1000 km | AM radio, Navtex | High attenuation at VHF | | Sky wave | HF (3–30 MHz) | Thousands of km | International broadcasting | Fading, seasonal variation | | Space wave | VHF/UHF+ (>30 MHz) | Line of sight (LOS) | TV, mobile, satellite | Requires tall towers |

The primary textbook titled " Antennas and Wave Propagation

Transmission lines, waveguide theory, and advanced antenna synthesis.
