Question 8.18: Compare the directivities of two arrays consisting of three ...
Compare the directivities of two arrays consisting of three identical elements separated by a half wavelength for the following two cases:
(a) Uniform array: (I_{-1} = I_{0} = I_{1} = 1 A).
(b) Binomial array: (I_{-1} = I_{1} = 1 A; I_{0} = 2A).
