Question

A corner reflector is converted to plane reflector when the corner angle is ______

(a) 90°

(b) 180°

(c) 45°

(d) 60°

I had been asked this question during an online interview.

This intriguing question comes from Flat Sheet Reflector topic in division Reflector Antenna of Antennas

Answer 1

Right option is (b) 180°

The best I can explain: For a corner reflector to become a plane reflector the corner angle must be 180°.

For a plane reflector N (current element) =1

\(α=\frac{π}{N}=π.\)
