—In this paper a programmable,beam-switching algorithm for planar phased array antenna is presented. Using micro-controller the planar array can be steered over 49 directions over the complete hemisphere. Each element is connected to delay lines and switching module. The bits at micro-controller output after being amplified by driver circuit are fed to the switching modules which control the insertion of fixed phase tapering. Switching is performed on a unique set of delay lines to steer the beam,in particular direction in the horizon. For high frequency application PIN diode is used as switch. In total 12 bits are used to select 49 beam,positions with some bit patterns being redundant. 188,Sanyal, Alfred, and Chakravarty
