Implementation a compact microstrip antenna for Wireless Fidelity (Wi Fi) At 2.4 GHz

Wireless Fidelity (Wi-Fi) is a wireless telecommunications technology developed by IEEE 802.11. Wi-Fi has a goal so that users can access the Internet anywhere. According to the IEEE standard for Wi-Fi, the network works at 2.4 GHz –2.484 GHz. This paper describes design and implementation of microstrip antenna on the wireless LAN card. All components of the antenna are placed on FR4 (e r =4.3) substrate with the overall dimension of 57 mm × 29.5 mm × 1.66 mm. The obtained results show that the proposed rectangular microstrip antenna achieves a good performed at outdoor and can be used as a client antenna with compact size. Also, a comparative study against a commercial antenna is described, and the proposed antenna shows better result than commercial antenna.
