A linear phased array antenna consists of eight elements spaced with d = element spacing.

(a) Give an expression for the antenna gain pattern (assume no steering and uniform aperture weighting).

(b) Sketch the gain pat- tern versus sine of the off-boresight angle . What problems do you see is using d rather than d = 2/2?
