Published by and now in its 4th revised and enlarged edition (as of 2019), the book is widely recognized for its systematic and accessible approach to a traditionally challenging subject.

: Covers electromagnetic fields, theoretical and practical antenna designs, and wave propagation phenomena in a single volume.

An antenna is a transitional structure between free space and a guiding device. Prasad covers this transition by exploring how electrical currents convert into electromagnetic waves.

The availability of the full book on Google Books often depends on copyright restrictions. Typically, you may find a preview or limited pages view. For full access, students often use the preview to check specific chapters or equations, while relying on library copies or authorized eBooks for the complete text.

If you provide me with the Google Books link or more context, I can try to:

Prasad avoids the overly mathematical rigor of Balanis (which targets graduate students) without dumbing down concepts. He uses what engineers call the block diagram approach . Every chapter begins with a conceptual model—for example, explaining a Yagi-Uda antenna not by starting with Maxwell’s equations, but by drawing a dipole, reflector, and directors. This pedagogical method ensures passing rates improve dramatically.

Detailed coverage of feeders, matching networks, and waveguides used for transferring power to antennas.
