“…Planar inter-digital capacitors (IDC) are mainly used for thick-film components where the metallic electrodes have to be applied after the sintering step. With composite thick films, metal-insulator-metal (MIM) structures could be realized in thick-film technology for the first time [7]. The capacitance of planar varactors can be calculated by conformal mapping methods [8] or by EM simulation tools.…”

“…One possibility is a selective screen printing of the BST only to areas which require the functionality. Figure 15 shows the realization of such a phase shifter based on a periodically capacitively loaded transmission line, where the BST has been selectively printed only in the areas where needed by means of ink-jet printing [7]. This is made possible by a low temperature sintering BST thick film, which enables the realization of a multilayer structure with a MIM configuration of the BST varactors between two photolithographically patterned bottom and top electrodes.…”

Modern communication platforms require a huge amount of switched RF component banks especially made of different filters and antennas to cover all operating frequencies and bandwidth for the targeted services and application scenarios. In contrast, reconfigurable devices made of tunable components lead to a considerable reduction in complexity, size, weight, power consumption, and cost. This paper gives an overview of suitable technologies for tunable microwave components especially for SatCom applications. Special attention is given to tunable components based on functional materials such as barium strontium titanate (BST) and liquid crystal (LC).
