A multi-functional microstrip compact antenna capable of steering the main beam to eight different directions in the elevation plane is conferred in this study. The compact antenna consists of a driven patch of to bring in the resonance to , for achieving enormous application in european radar service under Wi-MAX band. The conductive layer on the superstrate deflect the beam with an angle corresponding to the position of superstrate on parasitic layer, without considering complex phase shifters and associated circuits. Proper alignment of superstrate results maximum scanning angle ofwithof deflection angle. The directivity of the antenna is enhanced by manipulating the parameters of the superstrate. The gain of the antenna was improved up to  and the efficiency is improved up to  using engineered superstrate. The full-wave simulation as well as analytical study was done using the IE3D EM simulator.
