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...

This work presents the design, simulation, fabrication and measurement of a novel set of microstrip filters to perform the task of frequency discriminators. These filters' frequency responses are based on the balanced Gray-code. Results show that the use of the balanced Gray-code, as opposed to the traditional Gray-code, allowed 20% circuit size reduction by using 60% less resonators due to a change...
