Resumen:
A new compact reconfigurable frequency measurement device, based on interferometry is presented in this letter. The device combines the advantages of reconfigurability and fractal geometry. The interferometer uses a Wilkinson power divider connected to two microstrip delay lines; one of these corresponds to the second iteration of the Hilbert fractal curve. PIN diode switches are properly placed in the fractal delay line to achieve a 3-bit circuit, which operates in the 2.7-4.5-GHz range. The design and simulations presented are done using a full-wave electromagnetic simulator, and the frequency responses of the circuit are then shown and compared to measured results. © 2019 IEEE.
