Question

The half – power bean widths (HPBW) of an antenna in the two orthogonal planes are 100° and 60° respectively. The directivity of the antenna is approximately equal to

(a) 2 dB

(b) 5 dB

(c) 8 dB

(d) 12 dB

Answer 1

The correct option is ( C )

Explanation:

Given,

Half power beam width (θ_3dB)=100°

Half power beam width (Φ_3dB) = 60°
