Design a 10 x 8 element uniform planar array so that the main beam maximum is oriented along 0o= 10º, o 90°. 10 elements are in the a direction, 8 elements are in the y direction. For a spacing of dr = d, = 0.5A, find the 1. progressive phase shift between the elements in the r and y directions 2. directivity of the array 3. half-power beamwidths (in two perpendicular planes) of the array (in degrees) 4. amplitude of the first side-lobe relative to main beam maximum (in dB) 5. Repeat parts (2)-(4) for a Chebyshev amplitude distribution of -30 dB side lobes. You should use MATLAB for parts (2)-(5). Also include plots of the array factor power pattern in the two principal planes.
