The use of a phase-switched screen (PSS) boundary to control the radar cross-section (RCS) of a spiral patch antenna is investigated. A theoretical analysis based on a transmission line analogue is used to examine the concept and to provide basic design criteria. The design of an experimental system that includes a novel dual polarised active PSS boundary is described. Measured results are presented, which show that the demonstrator system provides active RCS control between 11 GHz and 13 GHz.
