About the Book: This book bridges theoretical principles and real-world applications in antenna design and wave-propagation analysis. With MATLAB readers gain hands-on experience in modeling and improving antenna designs. It simplifies complex relationships between antenna parameters radiation patterns and propagation characteristics in communication systems. Designed for undergraduate courses this textbook is also valuable for practicing engineers looking to update their knowledge in this critical field.
