Abstract
This paper presents a variation of the conventional ring resonator. It consists in an easier feeding way with direct connections instead of classical coupling accesses. Besides, the ring is capacitively loaded in order to allow implementation of narrow-band filter and reduce its physical length. A synthesis is proposed to design the filter. Based on this ring resonator cell, a second-order and fourth-order bandpass filters are designed at 2.9 GHz in microstrip technology. They are then characterized and compared to electromagnetic simulations.
