Abstract :
In this paper, planar Loop antenna with parasitic stub is presented. A design example is given in which a flexible antenna structure for Flexible E-paper in Bluetooth Band. The Proposed antenna is fabricated on flexible PCB. The polyimide film which has 125um thickness and 3.5 dielectric constant is used as a substrate for antenna. To confirm the characteristics of bended structure, bended and rolled antenna structures are presented. Measured results are compared with simulations and good agreement was observed. Proposed antenna has omni-directional radiation patterns over the operating bands and widen bandwidth than conventional planar loop antenna.
