Microstrip fractal-based phase shifter: An UHF phase shifter based on with Hilbert's fractal delay lines
This paper presents the design and simulated results of a Phase Shifter where the delay lines have been designed using the Hilbert's Fractal Line. Simulated results for fractal lines' group delay and PIN diode switch are also presented. Using the fractal lines allowed for a much more compact design when compared to traditional delay lines. Phase shift simulated results are in good accordance with theory.
