Abstract: | The aim of the paper below is to present the design approach, manufacture process and measurement results of a complete 360° phase shifter for Ku band controlled electronically. The phase shifter is based on microstrip technology and tunable reflective lines with varactor technology. This device allows to establish more than 360° phase variation with low insertion losses (2 dB in average), compared with devices found in literature. In this paper, a 12 GHz tunable phase shifter is analyzed, designed, simulated and prototyped. Eventually, prototype measurements are shown. |
