A Compact Wideband Printed Wire Antenna for Wireless Communications

This paper presents a compact dual-band printed-circuit-board wire antenna for wireless communications applications. The proposed wire antenna in F-shape with a shorted parasitic element can offer two separate impedance bandwidth of about 0.8 GHz (2.3 GHz~3.1 GHz) and 2 GHz (4.1 GHz~6.1 GHz) for a return loss less than -10 dB. Moreover, the antenna remains compact in size, making it a good candidate for Bluetooth and wireless local area network (WLAN) operation in the 2.4 GHz band and 5.2/5.8 GHz band. Measured results, including return loss and Smith chart, are presented
