Antenna And Wave Propagation By Kd Prasad Ppt Free Full -

The apparent height from which a reflected wave seems to return, assuming it traveled at the speed of light without bending. Summary for Presentation Slides

The extraction of Near-field (induction) and Far-field (radiation) components.

Single wire antennas provide broad omnidirectional coverage. For long-distance communication, point-to-point links require highly directional beams, achieved by grouping individual antennas into arrays.

): Directivity represents the maximum directive gain. It measures the concentration of radiation in a specific direction compared to an isotropic source.

To help you evaluate whether a PPT set is truly "full," here is a detailed checklist derived from the K.D. Prasad syllabus. antenna and wave propagation by kd prasad ppt full

Maximum Usable Frequency (MUF): The highest frequency that can be used for skywave communication between two specific points on Earth.

Designed to radiate perpendicular to the axis of the array ( ). This requires all elements to be fed in-phase (

These resources typically break down the massive textbook into manageable modules (e.g., Antenna Fundamentals, Antenna Types, Propagation).

The PPT (PowerPoint Presentation) based on KD Prasad's book covers a wide range of topics related to antennas and wave propagation. Some of the key topics covered in the PPT include: The apparent height from which a reflected wave

Converts electrical energy into electromagnetic waves (transmitting) and vice-versa (receiving).

Waves glide along the curvature of the Earth's surface.

The troposphere is the lowest layer of the atmosphere, extending from the Earth's surface up to roughly

, variations in temperature, pressure, and humidity create localized irregularities (turbulence) in the troposphere. These irregularities scatter small amounts of radio energy back toward Earth. This phenomenon enables secure, over-the-horizon communication links spanning up to several hundred kilometers without relying on satellites or the ionosphere. Duct Propagation (Super-refraction) To help you evaluate whether a PPT set

K.D. Prasad’s Antenna and Wave Propagation is considered a canonical text because of its systematic approach to electromagnetic theory. Unlike many contemporary texts that jump immediately into application, Prasad’s work is rooted in the gradual escalation of concepts—from Maxwell’s equations to the design of complex antenna arrays.

Direct line-of-sight path from the transmitter to the receiver, augmented by ground-reflected waves.
