// Data is taken from Example 17. The beam steers towards left of the axis with all parameters remaining in Ex 17 are same
c = 3*10^8; // velocity of EM waves in m/s
f = 2.5*10^9; // operating frequency in Ghz
S = 10*10^-2; // inter element spacing
theta = -10; // steering angle
// Calculations
lamda = c/f // Wavelength in m
phi = (360*S/lamda)*sin(theta*%pi/180)
phi1 = 0*phi // phase angle for element 1
phi2 = 1*phi // phase angle for element 2
phi3 = 2*phi // phase angle for element 3
phi4 = 3*phi // phase angle for element 4

// Output
