The present work deal with the design of a triple band, dual layer Microstrip Patch Antenna. The frequencies of three bands are 0.9GHz, 1.798GHz, 2.402GHz. the S-parameter and the gain characteristics as well as radiation pattern are investigated. The proposed antenna is suggested to be used in a mobile phone handset that covers three frequency bands which include GSM 900 (889-960), GSM 1800 DCS 1800 (1710-1885), Bluetooth and Wi-Fi/WLAN (IEEE 802.11 b/g/n) ISM 2450 (Industrial, Scientific and Medical) (2400-2500). The proposed antenna shows return loss (RL) of -17.79dB at 0.9 GHz; -18.5 dB RL at 1.798 GHz; and -44.2 dB RL at 2.4 GHz which are encouraging results. Designing and simulation of the proposed antenna were based on CST software package. Finally enact three bandwidth are got and the antenna shows an encouraging results for WLAN applications.
