Abstract

In this paper, a flexible monopole quasi-Yagi antenna printed on 50um thick polyimide substrate is designed for integration within modern flexible electronic devices. The antenna has a wide working band (5.22-6.6 GHz) that covers WLAN 5.8GHz (5.725-5.825GHz). Parameters changes of proposed modeling are analyzed to achieve desired impedance matching and resonant frequency. The reflection coefficient, gain and radiation efficiency are indicated to be still robust when the proposed antenna is under various bending directions. It is worth noting that radiation patterns have an effect when antenna is bent in the y-axis direction. The antenna prototype is fabricated and tested where the simulated results agree with measured ones.
