Phased array antenna technology is emerging as new way to deal with the growing demand for more powerful, cost effective and highly efficient wireless systems. This thesis presents phased array antenna at Ku-band for satellite system applications with steering capability to receive signals from different satellites. The proposed feeding structure consists of hybrid couplers and phase shifters in order to distribute the power and achieve the desired phase shift using varactors. The feeding network is series-fed circuit connected to an array of microstrip patch antennas, and it performs phase shifting in the intermediate frequency IF stage. The simulation is done using Advanced Design System (ADS) 2014 software. The simulation results show that a scanning range of 50 degrees has been achieved with gain variation of 1.3 dB.
