The antenna radiation pattern can be changed by changing the state of the diodes loaded in the phase varying reflector. A planar dipole antenna is used to excite the tunable reflector. By this technique the antenna beam can be steered from +300 to -300 in the broadside direction depending on the operating state of the diodes. Moreover, the state of the diodes can be addressed digitally and hence a steep gradient in phase can be achieved in the reflector. The antenna radiation pattern and the gain has been found stable all over its states. � 2017 IEEE.Book chapter
