Innovation is not a new phenomenon. Arguably, it is old as mankind itself.

In order to face with the new conditions and situations, enterprises are made to continuously search for new ways of production, namely offering new products or enhancing existing ones. In other words, they should continuously introduce innovations. But, what in fact do innovations represent?
Filters are substantial microwave components. RF/Microwave filters can be implemented using transmission lines. The frequency behaviour of microwave devices is affected by thermal expansion. In order to avoid interference with adjacent bands, microwave components must exhibit high temperature-stability in most communications applications.
