Abstract
A microstrip resonator (311) for a circulator/isolator is disclosed employing radial (815, 817, and 819) and circumferential (821, 823, and 825) slots to load the resonator and reduce the frequency of resonance. A resonator of small physical size is thus formed having a discontinuous outer ring (segments 807, 809, and 811) and a central triangle portion (827) each electromagnetically coupled to a ferrite element.
