Abstract Details

2018, Master of Science, Ohio State University, Electrical and Computer Engineering.
We present, for the first time, the design of a low-loss, 4-bit broadband switched-line phase shifter using vanadium dioxide (VO2) switches. The low-loss phase shifter exhibits average phase shift of 314 ° per dB of insertion loss and operates from 40 to 80 GHz. The dimensions of the 4-bit phase shifter is 0.75×1.35 mm2. This relatively small footprint, together with low losses, enables integration of the phase shifter with hybrid or passive electronically scanned arrays. Through full-wave simulation, the return loss was found to be better than 10 dB in all 16 states. Similarly, the minimum and maximum figure of merit for the phase shifter at 60 GHz were found to be 216 °/dB and 520 °/dB, respectively. Comparison of the simulated results for the designed phase shifter to experimental results reported in the literature, predicts that significant improvements can be expected from proposed phase shifters realized with VO2 switches.
