Abstract
A gapless ferrite structure for circulator or isolator includes a first base having a first flange and a first limit slot surrounded by the first flange, a second base having a second flange and a second limit slot surrounded by the second flange, a ferrite with two ends accommodated in the first limit slot and the second limit slot respectively, two limit magnets installed on the first base and the second base respectively and configured to be corresponsive to the ferrite to generate an attraction force on the ferrite, and two sealing units configured between an end of the ferrite and the first limit slot and between the other end of the ferrite and the second limit slot respectively. In this way, a gapless structure can be formed on a signal transmission path in a circulator or isolator.
