▎ 摘　　要

NOVELTY - The signal cross circuit structure has a different layer. Two paths of manual transmission line of artificial surface are provided. An intersection included angle is more than 30 degrees. A medium layer is arranged between artificial surface lines (1) of adjacent layers of the artificial surface. A signal is a radio frequency signal or a digital signal. A thickness of the medium layer is less than 1mm. The artificial surface line comprises a periodic unit of linear periodic arrangement and connected in turn. A forming material of artificial surface plasmons transmission line is metal or alloy or graphene. USE - Signal cross circuit structure for use in integrated circuit of satellite communication device (all claimed). ADVANTAGE - The characteristic of the artificial surface plasmon itself is skillfully used to the electromagnetic field energy constraint force, so as to reduce the signal coupling the routing cross, thus, realizing the purpose of multi-channel signal without affecting the cross passing. The design principle is simple, no needs professional calculation and design, is very good for popularization and use. The structure can contain more signal paths without influence cross because the structure is low to the cross signal path included angle, which is good for improving the integrated circuit design density. The cut-off frequency is adjusted by the structure size convenient, and which is easy to realize broadband even ultra-wideband structure, so the working bandwidth of the cross circuit design based on artificial surface is very wide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an integrated circuit. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a signal cross circuit structure. rtificial surface line (1)
