UWB antenna based on nanoparticles of silver on polyimide substrate

The aim of this paper is describing a design, realization and measurement of ultra wide band (UWB) antenna by inkjet printing technology on polyimide substrate DuPont™ Kapton^® HN 50.8 µm. For this purpose we used conductive silver based nano-ink AX JP-6n by Amepox Microelectronics LTD with particle size range between 3 – 7 nm in diameter. The realized antenna was designed and simulated in Ansoft HFSS™ 13.0. The frequency bandwidth of this UWB antenna is between 5.5 to 11.7 GHz that is according to decision of Federal Communications Commission. The impedance matching was realized by length of feeding element to 50 Ω. Paper includes the theoretical background of inkjet printing technology applied within UWB antenna realization.
