Some recent advances in the synthesis of isophoric sparse arrays for satellite communications

This paper discusses some recent advances in the synthesis of isophoric sparse arrays, with reference to satellite communications. In particular, we first summarize some of the synthesis algorithm recently proposed, highlighting their advantages and drawbacks. Then, we show that, depending on the particular application scenario for which the sparse array must be designed, a better tailored algorithm exists. The presented analysis is aimed at providing a useful tool for antenna engineers involved in the overall design of sparse arrays for satellite communications.
