Inkjet printing of a wideband, high gain mm-Wave Vivaldi antenna on a flexible organic substrate

A wideband, high gain mm-Wave Vivaldi antenna on a flexible substrate operating above 40 GHz with a realized gain greater than 9 dBi is demonstrated in this paper. This work presents both the highest frequency and highest gain antenna fabricated through inkjet printing to date. Inkjet printing allows for a rapid, low-cost, and environmentally advantageous fabrication of electronic components compared to traditional techniques and is currently advancing into mm-Wave operation for applications in high data-rate wireless communications.
