BANDWIDTH CONSIDERATIONS FOR A MICROSTRIP REFLECTARRAY [PDF]
Progress In Electromagnetics Research B, 2008 The paper describes a theoretical investigation into a limited bandwidth operation of a microstrip reflectarray. Two main factors limiting the bandwidth are considered. One is related to the requirement of phase compensation to convert a spherical wavefront launched by a feed into a planar wavefront. The other one is linked to the limited phasing range
