Question

Design a Dolph-Tschebyscheff broadside array of 8 elements, 25-dB sidelobe level, and with a
spacing of λ/2 between the elements to operate at 3 GHz. Choose a “rectangular patch” or a
"dipole" antenna as the array element that operates at 3 GHz. For the final antenna design,
determine the:

• Half-power beamwidth (in degrees). How much narrower or wider (in degrees) is this
half-power beamwidth compared to that of a uniform array of the same number of
elements and spacing?
• How much smaller or larger (in dB) is the gain (in dB) compared to that of a uniform
array of the same number of elements and spacing? Justify you answer. Do you expect
it? Why?
