Question:
In the two-element endfire array of Example 14.4, consider the effect of varying the operating frequency, f, away from the original design frequency, f0, while maintaining the original current phasing, ξ = −π/2. Determine the values of ϕ at which the maxima occur when the frequency is changed to
(a) f = 1.5 f0;
(b) f = 2 f0.
