Metal-Transfer-Micromolding of Air-Lifted RF Components

This paper reports a metal-transfer-micromolding (MTM) technique for simultaneous implementation of metallized high aspect ratio molded polymer RF passive components, as well as coplanar waveguide feeding structures, in a high performance and potentially cost-effective fashion. Applications of the MTM technique in air-lifted RF components such as Ka-band monopole antennas and evanescent mode cavity resonators have been demonstrated. A 21.5% 10 dB bandwidth for the monopole antenna, and an unloaded Q exceeding 500 for the resonators, are achieved from micromolded organic materials.
