RECONFIGURABLE INDEPENDENT MULTIBAND CPW-FED PRINTED F-ANTENNA FOR USB APPLICATIONS

摘要

A low-profile compact printed pentaband inverted Fantenna (IFA) for wireless universal serial bus is presented in this article. The proposed antenna consists of four printed arms capacitive loaded IFA in one side and one parasitic ring slot with open end on the other side. The capacitive plate is added at end of each arm for size reduction. The proposed antenna is designed to operate at long term evaluation band 8, GSM 1800 MHz; Bluetooth 2.4 GHz, WI-MAX 3.5 GHz, and WLAN 5.2 GHz. PIN diodes are used to reconfigure the operating frequencies by switching ON/OFF modes. The proposed antennas are studied using high frequency structure simulator version 13. The components interaction including housing case, laptop, desk, and chair are studied. The proposed antennas with and without PIN diodes are fabricated. The results show good agreement between simulated and measured results.
