Question

Corner angle of a corner reflector with 4 current elements is ______

(a) \(\frac{π}{4}\)

(b) \(\frac{π}{2}\)

(c) \(\frac{π}{8}\)

(d) 4π

The question was posed to me in an online quiz.

This intriguing question comes from Corner Reflector topic in chapter Reflector Antenna of Antennas

Answer 1

Right option is (a) \(\frac{π}{4}\)

For explanation: Corner angle of a corner reflector with 4 current elements is given by \(α=\frac{π}{N}\)

Given N=4

⇨ \(α=\frac{π}{N}=\frac{π}{4}.\)
