Abstract: The concept is demonstrated with a linearly polarized reflectarray designed to provide required coverage of wireless local area network (WLAN) access point at 5.8 GHz. The reflectarray is illuminated by a feed. The design process consists of two steps. First, a phase-only pattern synthesis technique is applied to obtain the required phase-shift distribution on the reflectarray surface which generates the shaped pattern. The second stage is determining the length of square patches in order to achieve the phase distribution synthesized in the previous step. The far-field generated by the vivaldi antenna is used to compute the radiation patterns of the reflectarray and the radiation patterns exhibit a shaping close to the requirements. To verify the proposed antenna, the reflectarray has been manufactured and tested in an anechoic chamber, showing a good agreement between theoretical and measured radiation patterns.
