Side Lobe Level Reduction for a Thinned Array and Aperture Sharing

In many applications, real estate allocated for antennas is constrained. Several different systems may need to co-exist within the same area, implying overlapping apertures and interlacing arrays.

In this study, we aim to optimize the usage of area by thinning the elements in one array in order to free up area for a different array. Our optimization approach ensures control of side lobe level, and aspires to minimize gain loss.

An algorithm that implements the optimization is presented and includes the combination of several methods that were developed to handle the increased side lobe level of the massively thinned array. The method was tested for the 1-D and 2-D cases.

Using these techniques, several arrays can be placed in a given aperture and work simultaneously. Development of such multi-functional arrays is explored and implemented. The results confirm that this procedure can save substantial amount of elements from the aperture with well controlled side lobe level and sets the ground for new designs of antennas arrays.
