Consider a 6-element linear array placed along the y-axis and each element is a small dipole oriented along x-axis. All the elements are fed with the same amplitude and placed a 0.5 lambda from each other. a. Calculate the progressive phase so that you have a peak radiation in the + z-direction, what is the radiated power in the +y, -y, +x, -x directions? b. What is the array type in part (a)? c. Calculate the progressive phase so that you have a peak at (theta = 90 degree, phi = 50 degree), d. Sketch the total E-plane pattern (XY-plane), in this part, you have to find all what you need to roughly sketch the pattern (nulls, maxima, HPBW, ... etc), (Be Patient) e. Calculate the total directivity, f. Use MATLAB to plot the E-plane pattern, g. Do you see any grating lobes? If yes, then reduce the spacing to push the grating lobe to the invisible region. What is your new d
