In this paper, a dual band flexible patch antenna presented for WLAN and X-band applications. The proposed antenna consists of truncated rectangular patch and defected ground structure. A 50 ohm microstrip line is used to feed the antenna. The size of proposed antenna is 25mm x 25mm. polyethylene terephthalate (PET) substrate is used in this design with relative permittivity value 3, loss tangent 0.008 and thickness is 0.14mm. The antenna design and simulation carried out by ansys HFSS which is based on Finite Element Method (FEM). The proposed flexible antenna operates at 2.45 GHz and 11.3 GHz with high gains 6.2 dB and 6 dB respectively. The bandwidth covers 2.4 GHz to 2.5 GHz for WLAN applications and 10 GHz to 11.6 GHz for X-band applications. The proposed thin and flexible antenna shows stable characteristics and which is suitable for WLAN and X-band applications
