SUMMARY:

This report presents the goals, methods and results from the Hilbert Fractal Geometry Based Microstrip Phase Shifter. It consists on the design of a 3-bit digital phase shifter, using delay lines with different lengths, designed with microstrip. Due to its space-filling property, the Hilbert fractal curve is presented in this work for the implementation of delayed lines with reduced sizes. Regarding the switching of lines, a switching circuit based on PIN diodes was simulated and implemented. In order to allow a more direct integration with other devices and systems where this device can be integrated, it was designed for a characteristic impedance of 50 ohms. The results for the delay lines, the switching circuit and the final device are presented in this work. Theoretical, simulation and measured results are compared.
