“…Because of these difficulties, many of new works in the field of microstrip reflectarray have returned to single layer structures involving new shapes of phasing elements. Examples include printed rectangular and square rings [8,9] and advanced elements shapes such as a windmill ring [10] and Malta cross [11] and compound-cross-loop [12]. The goal of this activity is to achieve a wide phase range and a slow phase variation (slope) as a function of the element's variable size.…”

Abstract-The paper reports on investigations into new schemes for dimensional scaling of the elements of a microstrip reflectarray to obtain a slower slope of the reflected wave phase characteristic. First, the phase response as a function of various shape elements is investigated when only one of their dimensions is varied. Next investigations concern the case when two dimensions or features of the element are scaled in a certain manner simultaneously. In the latter case, it is shown that phase responses of lower slopes with a minimal range reduction can be obtained. The feasibility of this concept is illustrated for dipoles, rectangular patches, and square and circular rings. Comparisons of the obtained results show that twodimensionally scaled square and circular rings offer much better phase responses than those observed for dipoles and patches.
