Abstract
The adaptation of the LTCC (Low Temperature Cofired Ceramics) process for an unusually high number of layers (up to 50) will be described and explained in this paper. Special attention will be paid to lamination, debindering, and cofiring of the LTCC stack. The influence of necessary process variations on electrical properties such as permittivity will be studied. Very often the number of layers is determined by the complexity of the circuit. Here a minimum substrate height is required for the electrical performance of a patch antenna, particularly in terms of bandwidth. A dual band antenna for two Galileo bands at 1.58 GHz and 1.18 GHz was realized as a combination of two coupled patches. Circular polarization was attained by separately feeding each patch with a hybrid coupler. These features add further layers to an already considerable substrate height.
