This paper presents the design of a thinned reflectarray. The phase‐shifting elements are slotted rectangular microstrip antennas with via connection to the ground plane. They are disposed in a regular grid. The thinning procedure is used to determine which elements may be removed, according to the desired radiation pattern, without significant change in directivity. For this approach, a genetic algorithm is proposed. © 2005 Wiley Periodicals, Inc. Microwave Opt Technol Lett 46: 559–562, 2005; Published online in Wiley InterScience (www.interscience.wiley.com).
