Interest in wireless body area networks (WBAN) operating in the millimetre-wave regime (60 GHz) is increasing due to concerns over the security of data transfer. Obtaining fine pitch in this frequency regime is essential, as the design dimensions scale inversely with wavelength. In the area of wearable electronics, printing onto fabrics is challenging, due to the porosity of the material. Some researchers have considered screen printing for realising interconnects onto fabrics. In this paper, inkjet printing is investigated for fine pitch printing on a nonwoven fabric targeted for high frequency applications.
