A novel circular slot antenna is proposed for wireless local area network (WLAN) applications. By applying a monopole on the opposite side of the circular slot etched on the ground plane, a resonant frequency band is excited at about 2.4 GHz, with impedance bandwidth (return loss > 10 dB) from about 2.3 to 2.8 GHz, which covers WLAN 2.4 GHz and worldwide interoperability for microwave access (WiMAX)...
A compact dual-band antenna with modified open U-shaped slot is proposed. The antenna is mainly composed of a patch with modified open U-shaped slot and a T-shaped feed line. The dual-band characteristic is obtained by folding the upper strips of the patch. The proposed antenna is fabricated and tested. The measured results show that the proposed antenna covers 2.38–2.52 GHz and 5.0–6.1 GHz with S11<−10...
