Triple Band Microstrip Patch Antenna with Dual U Slot For WLAN/WIMAX Applications
In this paper, a dual U-slot microstrip patch antenna with U shape slot cut in the ground for wireless communication application such as WiMAX and WLAN is presented. The microstrip U shape patch antennas are gaining attenuation in various WiMAX (Worldwide interoperability for Microwave Access) applications since last two decades. The proposed antenna is designed using FR4 substrate having dielectric constant 4.4 with microstrip feeding method. The designed antenna generates the triple frequency band of 2.40GHz, 3.25GHz and 5.35GHz which can be used in industrial, scientific and medical radio band under WLAN interoperability, WIMAX and wireless networks respectively.
