Design a uniform ordinary end-fire array to have a half power bandwidth (HPBW) no greater than 100°, namely :
i- find the number of elements N, take the inter-element spacing d=λ/8.
ii- find the relative side lobe level.
iii- now, repeat your design according to Hansen-Woodward priciple and find the current phases and new HPBW.
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
