Design of Planar Monopole Antenna for 2.4 GHz WLAN

T-Shape planar monopole antenna has low profile and can fed by 50 ¿ micro strip line for wireless local area network (WLAN) at 2.4 GHz frequency. The design is achieved good Return loss matching for simulation and experimental result. The gain of the antenna is ≥ 4 dB and VSWR bandwidth ≤ 2. The radiation pattern and directivity of proposed antenna also presented. For analyzing the transfer function characteristics, it shows that the signal corresponding to 2.452 GHz (2.256-2.687 GHz) band serve the antenna is suitable for WLAN application.
