Furthermore, the text provides an exhaustive classification of antennas. It covers aperture antennas, horn antennas, and parabolic reflectors, which are critical for microwave communication. Perhaps most importantly for the Indian engineering curriculum, it dedicates substantial chapters to "Antenna Arrays." The mathematical formulation of array factors, binomial arrays, and broadside/end-fire arrays is presented with clarity, offering students the tools to design antennas with specific directional properties. The inclusion of specialized topics like the Yagi-Uda array and log-periodic antennas provides historical and practical context for television and high-frequency communications.

Years later, the valley—once a place of dropped calls and delayed help—became a quiet hub of grassroots engineering. Young people learned to design antennas from scrap, elders taught the rhythms of fog and wind, and clinics coordinated over radios that sang true. Mira’s nautilus helix evolved into variations: arrays tuned to shepherd waves along canyon corridors, lightweight foldable units for mountain medics, and whimsical sculptures that doubled as public art and communication gear. The inclusion of specialized topics like the Yagi-Uda
While modern engineering has moved toward software-defined radios and antenna design using simulation tools like HFSS or CST, the theoretical foundation provided by Prasad remains relevant. A simulation tool can show a radiation pattern, but it cannot teach the intuition behind why the pattern is shaped that way. Prasad’s text provides that intuition. Young people learned to design antennas from scrap,
