title = "High layer count in LTCC dual band antenna for galileo GNSS",
abstract = "The adaptation of the LTCC (Low Temperature Co-Fired Ceramics) process for unusual high number of layers (up to 50) shall 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 like 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.",
