Abstract

1428384 Junction circulators GENERAL ELECTRIC CO Ltd 21 Nov 1973 [21 Aug 1972] 38909/72 Heading H1W The central planar conductor 16 of a stripline or triplate-line junction circulator is provided with slots 38, 40, 42 extending from the periphery and arranged to be symmetrical with respect to rotations of 120 degrees. The slots result in a decrease in the frequency of operation. They need not be radial or parallelsided, and they may have any angular position relative to the lines 18, 20, 22, e.g. as indicated by the alternatives 381, 40<SP>1</SP>, 42<SP>1</SP>. The invention is applied to a junction circulator of conventional construction in which the lines 18, 20, 22 are matched to the junction by line sections 28, 30, 32 of increased width. It may also be applied to a triplate construction (Figs. 3, 4, not shown).
