Abstract

The design of the slot antenna with three bands for worldwide interoperability for microwave access (Wi-Max) and Wireless Local Area Network (WLAN) has been presented. This antenna consists of a leaf shaped slot and a triangular parasitic patch. Area of the designed antenna is 40×40 mm² and height of the designed antenna is 1.6 mm. For the purpose of feeding, a 50Ω microstrip line is used in this design. To improve the bandwidth and gain of the designed antenna, a triangular parasitic patch is used. After doing a parametric study on the parameters of the designed antenna a triple frequency band is presented. Simulated bandwidth, defined by -10db return loss can reach an operating bandwidth of 4GHz at the operating frequency 4.5GHz. The simulated result signifies that the effective bandwidth of the designed antenna is 84.15% from 2.65GHz to 6.55GHz with -10db return loss. After getting the simulated results, the designed antenna can cover the frequency band 3.27-3.97 GHz for Wi-Max systems and 5.17-5.93 GHz for the IEEE 802.11a WLAN systems.
