Abstract :
This letter is focused on the design of thinned planar arrays achieving simultaneously the two following requirements: 1) a given beamwidth in the broadside direction and 2) a given peak side-lobe level in a specified sub-domain of the visible region. It is seen that Cantor spiral arrays are excellent candidates. Peak sidelobes of the order of $- 20~ dB$ and a beamwidth of 0.6 $^circ$ are obtained with only 200 radiating elements.
