Abstract :
A X-band reconfigurable active phased array antenna system is presented. The phased array system consists of interconnected tile modules of which number can be flexibly changed depending on system requirements. The PCB integrated tile module assembles 4×4 patch antennas and flip-chipped phased array 0.13-μm SiGe BiCMOS ICs with 5-bit IF phase shifters. The concept of scalable phased array is verified by narrowing beamwidth in beamforming pattern and improving SNR in data transmission of 64-QAM OFDM signal as increasing the number of antenna elements.
