We presented a novel process for constructing high conductivity CNT surfaces. This is done by growing high density CNTs on light-weight and highly flexible polymer substrates. The proposed vertically aligned CNT printing technology can also be adapted for constructing flexible RF circuits integrated on a variety of commercial and defense related applications. Given the desirable RF and mechanical...
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...
Many mobile structures (aircrafts, ships and automobiles) require conformal antennas for high data rate connectivity, which brings the need for material compatibility and for structurally reinforced antennas. The latter requirement is particularly challenging for small platforms since a large antenna is needed at these frequencies. For small unmanned air vehicles (UAVs) spanning a few feet, it is...
Low-cost and convenient fabrication techniques are of significant interest for flexible and multifunctional electronics industry. This paper has presented a versatile fabrication process for direct printing of conducting patterns for RF circuits on ceramic-PDMS composite substrates. In order to illustrate this technique, a three-dimensional design of a GPS antenna is produced. Through this promising...
