1.	What is the phase shift of the array is the scan angle is 30° and spacing distance is λ/2?(a) \(\frac{π}{2} \)(b) π(c) 2π(d) \(\frac{π}{4} \)I got this question by my college professor while I was bunking the class.My question is taken from Phased Array topic in portion Phased, Adaptive and Binomial Arrays of Antennas
Answer» The CORRECT CHOICE is (a) \(\FRAC{π}{2} \) To explain: The PHASE \(ᴪ=\frac{2π}{λ} dsinθ=\frac{2π}{λ} \frac{λ}{2} sin30=\frac{π}{2} \)
