Abstract :
This paper presents the design of the circularly polarized slot antenna on the flexible substrate for ultra wide band (UWB) high band application. We applied two slots which are crossed perpendicularly to obtain circularly polarized wave. By optimizing the lengths and widths of the antenna slots and substrate, wide band impedance matching can be realized. Impedance bandwidth of proposed antenna is 5.60 GHz from 7.11 to 12.71 GHz and the antenna size is 16 mm × 16.3 mm × 0.254 mm.
