Optimization of MEMS Ku-band phase shifter

Summary form only given. Microelectromechanical system (MEMS) switches and phase shifters built from these switches have been demonstrated in several papers (Guan-Leng Tan et al., 2002, 2003; Hacker, J.B. et al., 2003; Kim, M. et al., 2001; Pillans, B. et al., 1999). Potential applications include: military radar, including active and passive electronically scanned arrays; aviation radar; reconfigurable wireless networks; satellite broadband communication networks. MEMS phase shifters offer low insertion loss and parasitics. In addition, the MEMS phase shifters may provide cost and weight advantages for large arrays. The poster addresses the optimization of a 15 GHz switched-line phase shifter in which every delay bit is implemented separately. The size of the phase shifter is one area to be optimized. Also, it is intended to develop a hybrid design to reduce the number of switches in the phase shifter.
