METAL-TRANSFER-MICROMOLDING OF AIR-LIFTED RF COMPONENTS
Yanzhu Zhao, Yong-Kyu Yoon, Xiaosong Wu and Mark Allen
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.
Keywords: air lifted monopole antenna, evanescent mode resonator and micromolding
