This article presents a novel flexible wideband ink-printed dipole array antenna for emerging medical sensing and human body wearable electronics applications. The antenna operates from 23 GHz to 30 GHz, including 24.5 GHz and 28 GHz for 5G application. The antenna consists of simple layered screen printed structure, which is suitable for rapid prototyping with printing technology. Both simulation and measurement results are presented, which shows a percentage bandwidth of 26.4% and a maximum forward gain of 4.2 dBi. Further investigations are conducted to analyze the effects of imperfect fabrication process on the antenna performance.
