ZHANG, S. ... et al, 2015. Novel 3D printed synthetic dielectric substrates. Microwave and Optical Technology Letters, 57 (10), pp. 2344-2346.
This letter presents dielectric properties of air filled synthetic substrates fabricated in a single process using three-dimensional printing. The permittivity and loss tangent of a given sized substrate can be changed by controlling the air infill volume fraction.
