Flexible and wearable 2.45 GHz CPW-fed antenna using inkjet-printing of silver nanoparticles on pet substrate

This article demonstrated a fully printed CPW-fed antenna based on silver-nanoparticles for ISM that is flexible, wearable, and reversibly deformable. The proposed antenna consists of nano-silver ink, a conducting material used as a radiating patch and ground planes printed on the polyethylene terephthalate flexible substrate. The fully printed antenna was fabricated and the radiating properties were investigated. The simulated and measured reflection coefficients are approximate to-31 dB and approximate to-23 dB, respectively. Meanwhile, the -10 dB bandwidth is approximate to 530 MHz and the obtained VSWR is approximate to 1.3. Radiating properties were characterized and agree well with the simulation results. The material and fabrication technique illustrated here could be extended to achieve other types of flexible antenna with more complex patterns for wearable electronics applications.
