JCS_V5_N2_RP4 A Compact Triple Band Monopole Antenna With U-Shaped Slots For Wireless Applications Garima Jaiswal Journal on Communication Engineering and Systems 2277-5242 5 2 25 29 Triple Band Antenna, WCDMA, WiMAX, WLAN, Microstrip Patch Antenna A compact size triple band microstrip patch antenna for WCDMA and Bluetooth, Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Local Area Network (WLAN) has been proposed. This antenna is applicable for all wireless application such as Bluetooth, WiFi, WLAN and WiMAX. It is very compact to other existing antennas. This proposed antenna consists of patch with U-shaped Slots, symmetric stair type structure microstrip feed and finite ground plane. It operates over the frequency ranges, 1.9-2.6 GHz, 3.3-3.9 GHz and 4.4-7.1 GHz and suitable for WCDMA and Bluetooth (1.9-2.6 GHz), WiMAX (2.5 / 3.5 / 5.5 GHz), WLAN (2.4 / 5.2 / 5.8 GHz) and WiFi (5 GHz) and also provides band 3 rejection between that frequency bands. The proposed antenna is compact (15x15x1.6 mm ) with good return loss and wider bandwidth. February - April 2016 Copyright © 2016 i-manager publications.
