Flexible Antenna Printing Technology of silver nanoparticles (AgNPs) ink on Polyethylene Terephthalate (PET) Material Substrate for Vehicle-to-Everything (V2X) Applications

Abstract

Flexible antennas are important components in addressing a growing number of V2X applications. To mitigate vehicle-shaped effects, a flexible and compact circularly polarized (CP) Dedicated Short Range Communication (DSRC) antenna is designed based on a sequential phase (SP) feeding network and sequentially rotated (SR) elements. The antenna is printed on polyethylene terephthalate (PET) substrate by using a PCB printer using silver nanoparticles (AgNPs) ink. The fabricated antenna has a dimension of 27×27×1 mm3 which is printed precisely to radiate in CP with an axial ratio of 1.34 and gain between 5.3 and 5.7 dBi. The printed antenna’s precision is proven to operate effectively from 5.85 to 5.925 GHz, with a fractional impedance bandwidth (FBW) of 1.27%.
