Abstract
A method of designing a reflectarray including a substrate having a surface perpendicular to a predetermined axis, wherein elements are disposed on the substrate. The method obtains a reflection phase of the elements as a function of a design parameter such as element spacing, when a radio wave enters the arranged elements, and stores a relationship between the reflection phase and the design parameter in a memory. Here, the design parameter is equally set for the elements. The method repeatedly determines, for each of the elements, the design parameter of a specific element in accordance with the relationship. The function of the design parameter has a range of almost 360 degrees with respect to a range of the design parameter. The reflection phase is the continuous function of the element spacing such that two resonant points occur at which the reflection phase becomes zero.
