ABSTRACT:
A transmission line of striptype includes a dielectric having a local dielectric constant alternating between at least two different values. It can be manufactured by applying a first layer (3) of a material having a first dielectric constant ∈1 to a base (1), thereupon patterning the first layer to produce recesses, then applying a second layer (5) of a material having a second dielectric constant ∈2 over the first layer to at least completely fill the recesses to obtain a flat surface, and finally applying a conductor on top of the produced structure. The transmission line can be used for example for various types of filters and delay lines, is simple and has a low cost for its manufacture and can give a space-saving design of different components.
