Practical Bending Studying on UWB Pentagonal Flexible Antenna

This paper presents the effect of bending on UWB pentagonal shape antenna. The antenna is considered to be used for modern UWB wearable technology including RFID, mobile devices, wearable GPS, to mention a few. The antenna is built on polyimide substrate of 50um in thickness. The effect of bending has been studies in term of S-parameters and radiation pattern. The pentagonal shape UWB antenna bandwidth before and after the bending is 111.6% which extended from 2.93 GHz to 10.3 GHz. While the gain of the antenna is averaging around 3dB at 3.5 GHz, 5.2 GHz, and 5.8 GHz before and after the bending. The antenna is suitable solution for modern wearable technology.
