1- Design a 4-element broadside array with equal side lobe level of -20 dB relative to the peak value , take the inter-element spacing d=λ/2 , find the resulting beamwidth to null .
Added by Thomas C.
Step 1
In this case, we have a 4-element broadside array, which means we have 4 antennas arranged in a line. The side lobe level is -20 dB relative to the peak value. This means that the power of the side lobes is 20 dB less than the power of the main lobe. In terms of Show more…

Design a 19-element uniform linear scanning array with a spacing of λ/4 between the elements. (a) What is the progressive phase excitation between the elements so that the maximum of the array factor is 30° from the line where the elements are placed? (b) What is the half-power beamwidth (in degrees) of the array factor of part a? (c) What is the value (in dB) of the maximum of the first minor lobe?
