Summary:
At current stage, the antennas for WLAN access points are the linear dipole, slot array, and microstrip antenna, ect. [1-2]. These antennas are not suitable for field radiating in the large room and complex shaped room because of power loss in unnecessary directions. In many applications, reflectarray antenna requires radiation patterns to be shaped such that the pattern contour fits the shape of the desired coverage region [3] which the antenna is placed on the ceiling. The shaped contour radiation pattern reduces wasted transmitted power by minimizing the illumination of unwanted areas such as out of the room. The advance of the reflectarray antenna is low profile and light weight to easier placement and deployment on the WLAN indoor [4]. This paper will present the synthesis and simulation results of reflectarray. The physical optics(PO) [5] and optimization method are employed for reflector surface shaping to produce the desired contoured beam
