Antenna And Wave Propogation MCQ Questions And Answer | Electronics and Communication Engineering

Antenna and Wave Propagation (AWP) is the cornerstone of modern wireless communication. It explores how electromagnetic energy is transitioned from a guided medium (like a cable) into free space and how those waves travel across the earth or through the atmosphere to reach a receiver. From the Dipole Antenna in early radio to the massive MIMO arrays in 5G technology, AWP defines how we connect without wires.

Beyond the complex Maxwell’s equations, this field carries a profound human touch. It is the technology of connection, enabling a soldier to call home from a remote post, a doctor to perform robotic surgery from miles away, and global positioning systems to guide travelers safely.

Antenna Gain, Radiation Resistance, and propagation modes—such as Ground Wave, Sky Wave (Ionospheric), and Space Wave—is essential for excelling in competitive exams like GATE, IES, and ISRO. It is the science that turns the invisible spectrum into a global bridge for human interaction.
