Abstract :
In this paper, we introduce a printing technique to reliably metallize PDMS-ceramic composites for multilayer integration. Strong polymer-metal adhesion and stable mechanical/RF performances are achieved via the following steps: (1) surface masking, (2) surface modification, (3) titanium adhesion layer and (4) electroplating. We note that the surface modification and electroplating are newly introduced steps to overcome above mentioned fabrication challenges and therefore making PDMS attractive for RF applications. Below, we discuss these steps and present two examples, a single-layer hybrid for circular polarization (CP) feeding and a patch antenna. Techniques for 3-D fabrication and multilayer integration are also elaborated using a hybrid-embedded GPS antenna and a multilayer microstrip directional coupler.
