Abstract

A spherical rotating joint operating at millimeter wavelength is proposed here. Unlike the traditional rotating joints, this is made of two half spheres in which the spherical hybrid mode HEll operated. The coupling effect of the capacitances due to the gap between two half sphd'res maintains electrical continuity. The measurements indicate that the constant output is achieved while the joint being rotating over 0-- Orsolide angle range, the V.S.W.R. are less than 1.5 and the insertion loss are lower than 1.0 dB from 34.5 GHz to 35.5 GHz.
