Abstract
1,127,758. Circulators. SOC. ITALIANA TELECOMUNICAZIONI SIEMENS S.p.A. 24 Jan., 1966 [15 Feb., 1965], No. 3043/66. Heading H1W. The sides of the ferrite element 1 in a microwave junction circulator are coated with dielectric material 4, e.g. PTFE to a thickness equal to about 10 to 30% of the maximum transverse dimension of the element. The Specification describes an H-plane Y-circulator using a ferrite element spaced from the opposite broad walls of the junction by triangular dielectric elements 2.
