Abstract
In this paper, we present two compact ultra thin and flexible printed monopole
antennas intended for integration with flexible displays, such as flexible organic
light-emission displays (FOLEDs) and active matrix electro-phoretic displays (AM-EPDs).
The proposed antennas are designed to provide Wireless local area network (WLAN) and
Bluetooth connectivity for flexible displays. The first design is a dual band antenna
operating at 2.45 GHz and 5.2 GHz while the second is a single band antenna operating at
2.4 GHz. Both antennas were printed on a Kapton polyimide-based substrate with
dimensions (35 mm×25 mm) and (26.5 mm×25 mm) for the dual and single band
respectively. Antenna properties, such as gain, far-field radiation patterns, scattering
parameter S<sub>11</sub> are provided. Moreover, the effect of folding/bending was performed
experimentally on both designs to study its influence on the antennas performance. The
proposed compact, thin and flexible designs along with antennas characteristics are
perfectly suitable for integration into flexible displays for WLAN and Bluetooth
connectivity.
