A reconfigurable electromagnetic interface to ease requirements on phased array common modules

摘要

This paper describes how a reconfigurable electromagnetic interface (REI) can, at the antenna element level, enhance the affordability and shorten the development lifecycle of platform-based phased arrays. These improvements are enabled by a significant degree of component and process reuse and also by easing the design requirements on phased array common modules. Among the benefits of an REI are: tunable frequency selectivity, tunable polarization selectivity, tunable phase, four times the allowed common module footprint (area), and no balun requirement.
