The wave guide and the transmission line in the gap between the parallel conduction surface

摘要

Topic Frequency is high excessively, the existing transmission line and loss of the wave guide are too large, or, in the scope of supply which is required, when being possible to produce costwise efficiently, the electromagnetic transmission line which is profitable, microwave device such as wave guide and those circuits is actualized new method.SolutionsAs for new technology, coaxial line, hollow circular cylinder wave guide and micro strip line,It is something which intends the fact that it substitutes to the other basis restraint transmission line in high frequency. The microwave device it is actualized to the gap whose between of two parallel surfaces of the conduction material is narrow making use of one texture or multilayer structure among the surfaces. The magnetic field exists mainly in the gap, does not exist in texture or layer structure itself, loss is small with that. For example the high frequency device furthermore is categorized to the multilayer structure between two surfaces, it has the electric conduction element of one or more such as metal ridge or two surfaces or one groove among the metal strips. The wave is spread alongside the electric conduction element. Metal connection of two metal surfaces is not necessary. At least as for one among the surfaces, the wave the ridge, the groove or the strip, in at those time, has the expedient which prohibits the fact that it is spread to other direction. In very high frequency, in IC package, or, to actualize in the tip/chip itself it is possible the gap wave guide and the gap line. Selective figure Figure 1
