📊 Antennas and Microwave Engineering
Q. Lens antennas are classified into two types. One being fast antenna, the other one is:
  • (A) slow antenna
  • (B) delay antenna
  • (C) dynamic antenna
  • (D) none of the mentioned
💬 Discuss
✅ Correct Answer: (B) delay antenna

Explanation: in delay lenses, the electrical path length is increased or the wave is retarded by the lens medium. dielectric lenses and h-plane metal lenses fall in this category.
