Radiaton Pattern Reconfiguration Using Parasitic Elements

A parasitic surface based reconfiguration technique for microstrip antenna beam steering has been presented and discussed in this paper. This concept can be used in reconfigurable antennas without additional modification on the basic design of an antenna. This paprasitic layer based antenna is designed using array of 5 by 5 pixel surface which can be connencted or disconnected depending upon required configuration so as to steer antenna beam in particular direction such as -30°, 0° and +30°.
