This paper investigates the effects of bending on the performance of a flexible dual-band printed monopole antenna designed to work for GPS, WLAN, and WiMAX applications. The antenna is printed on a Polyimide substrate with a relative permittivity of 4.3 and thickness of 25 pm. The antenna is fed by a coplanar waveguide transmission line to enhance the impedance matching over the wide operating bandwidth...
The effects of thickness and dielectric constant of flexible substrates on the performance of a circular planar monopole antenna (PMA) is reported in this paper. The antenna is printed on a flexible Polyimide substrate and fed by 50 Ω microstrip line. Results revealed that substantial effect on the antenna performance due to substrate thickness and material even if the radiating structure is ungrounded...
