Beam scanning have found great demand in the field of wireless communication, satellite communication, radar, etc. [1,2]. These applications are generally covered by phased array antennas [3], where several elements are grouped together in a linear or planar special configuration. The radiated beam is determined by the vector addition of the electromagnetic fields radiated by the individual elements. Present proposal a novel technique of Tunable Multi Layer Multi Dielectric High Impedance Surface (TMMD-HIS) is embedded with array antenna, making it possible to obtain a beam scanning angle of 40 degree (from -20 degree to +20 degree) without the need of expensive active components. The major advantage of proposed concept is that the array have a negligible mutual coupling between radiating element this is happen because of suppression of surface wave. In built phase shifting is provided which reduces the structure size and proportionally cost . simulated results showing the effectiveness and compatibility of proposed concept.
