In this book, the two-dimensional planar array is designed to reduce the sidelobe levels without any extra processing for the feeding currents or changing the elements locations. The design will trim the elements at the four corners with a specific circular masking function which results in a redistribution of the sidelobes so that the two major planes of sidelobes at th=0 and 90 degrees are reduced at the cost of increasing other negligible sidelobes. The new masked two-dimensional array has the advantage of easier manufacturing over the concentric circular arrays while maintaining almost the...
