Mathematical model for spiraphase-type infinite reflective array based on slot ring resonators with pin diode switches

Abstract

Mathematical model has been developed to predict the characteristics of spiraphase-type phased array based on slot ring resonators with p-i-n diode switches. It is demonstrated that this array can redirect an incident circularly polarized wave in the directions determined by reflection elevation angles up to 60deg in a 20% frequency band with total loss less than 3.5 dB.
