60 GHz Antenna on Metallic Nanowired Membrane Substrate

摘要

This work presents the analysis of the novel metallic nanowired membrane (MnM) substrate for designing antennas at the 60 GHz frequency band. The fabrication process of a rectangular patch antenna on the MnM-substrate is presented in detail. The antenna is fed through a modified microstrip line with slow-wave effect in order to reduce the feed line width. The fabrication is done in two phases, first the microstrip circuits are fabricated on a 50-μm-thick membrane; then it is assembled on a mechanical base to accommodate the two different substrate thicknesses used for the antenna and the slow-wave transmission line. The structure is simulated using a 3D EM software and the results indicate this substrate is a viable choice for antenna design, however gain increasing techniques must be used because of the high dielectric constant of the substrate.
