Question

HPBW of H-plane horn is (in degrees) _____

(a) \(\frac{56λ}{h_h} \)

(b) \(\frac{67λ}{h_h} \)

(c) \(\frac{λ}{56h_h} \)

(d) \(\frac{λ}{67h_h} \)

This question was addressed to me in unit test.

This question is from Design topic in portion Horn Antenna of Antennas

Answer 1

Correct option is (b) \(\frac{67λ}{h_h} \)

Easy explanation: HPBW of H-plane horn is  \(\frac{67λ}{h_h} \)  where hh the aperture dimension of H-plane horn.
