Abstract :
A novel inductor configuration, consisting of a two-dimensional photonic bandgap (PBG) periodical array in addition to the existing inductor, e.g., spiral inductor, is built, analyzed, and tested. Measurements show that a one-turn, 13.1 mm long spiral inductor (3 mm by 3 mm) placed on a PBG ground plane made of unit cells using coupled inductors of dimension 1.5 mm by 1.5 mm on Roger 4003/sup TM/ substrates can increase the inductance by 34%, reduce the series resistance by 45%, improve the Q-factor by 33%, and extend the peak Q-factor frequency by 14% as compared to the conventional spiral inductor of the same size. Dispersion characteristics of both PBG-enhanced and conventional spiral inductors are reported.
