K.D. Prasad’s Antenna and Wave Propagation

If you’re an engineering student (especially in ECE), you’ve likely heard of . It’s a standard textbook for B.Tech/BE courses, known for its clear explanations of radiation patterns, array antennas, ionospheric propagation, and transmission lines. Unit 5: Wave Propagation The book is structured

• Basics of electromagnetic waves: Maxwell’s equations, wave equation, boundary conditions.
• Transmission lines and waveguides: line parameters, impedance, reflection, standing waves, Smith chart basics.
• Antenna fundamentals: radiation mechanism, current distribution, radiation fields, gain, directivity, radiation pattern, beamwidth, polarization, and efficiency.
• Point and line sources: dipoles (infinitesimal, half-wave), monopoles, loops.
• Array antennas: array factor, pattern multiplication, synthesis methods (e.g., binomial, Chebyshev), mutual coupling basics.
• Aperture antennas and horns: aperture fields, directivity, gain calculations.
• Microstrip (patch) antennas: modes, feeding techniques, design considerations (if included).
• Antenna measurements: pattern measurement, gain measurement methods (comparison method, gain-transfer), impedance measurement.
• Propagation mechanisms: free-space propagation, ground reflection, tropospheric and ionospheric effects, path loss models, fading basics (slow/fast, small-scale), link budget fundamentals.
• Practical design examples and solved problems (common in such texts).
