Abstract
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. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2344–2346, 2015
