Abstract :Adaptive antenna is emerging area in telecommunication industries which has ever-growing scope and application in RADAR as well as communication industry. Nowadays DOA estimation and beam forming are wildly used in RADAR and 4G/5G technology. In this paper, we proposed a system which will determine the direction of transmitting antenna (DOA estimation) using phase detector and transmit signal in that direction (beam forming). This process makes antenna more directives and increases the efficiency. In the proposed system one transmitting antenna is transmitting at frequency 2.4-2.5 GHz from a certain angle. There are two receiving antennas which receive signals but there is some phase/time/amplitude difference between those two antenna signals. From that phase/time/amplitude difference, the exact angle of arrival of signals is calculated. After determining the angle of arrival using VCO, power divider and phase shifter the direction of transition of antenna signal is changed this method is called beamforming. Use of the phase detector circuit reduces complexity and need of use of complex algorithms like MUSIC, ESPRIT etc., this also reduces overall cost.
