Which of the following are antenna types listed?

• A. Dipole
• B. Satellite dish
• C. Yagi
• D. All of the above

Answer: (D)

Antennas come in many shapes, but they share the idea of converting electrical signals into radio waves and shaping how those waves are radiated. A dipole is a basic two-element rod that radiates in a broad pattern and is one of the simplest and most common antenna types. A Yagi is a directional array with multiple elements that boosts gain in a specific direction, making it useful when you want to focus signals. A satellite dish uses a parabolic reflector to concentrate signals onto a feed horn, enabling strong communication with satellites. Since each of these is a recognized type of antenna, the correct choice is all of the above.
