%X In this article, a compact microstrip-fed printed dual band antenna for Bluetooth (2.4-2.484 GHz) and UWB (3.1-10.6 GHz) applications with WLAN (5.15-5.825 GHz) band-notched characteristics is proposed. It is demonstrated that dual band characteristics with desired bandwidth can be obtained by using a fork shaped radiating patch, whereas, band-notched characteristics can be obtained by etching two L-shaped slots and two symmetrical step slots on the rectangular ground plane. The proposed antenna is simulated, fabricated and tested. The structure is fabricated on a low cost FR4 substrate having dimensions of 50 mm (L) ¡Á 24 mm (W) ¡Á 1.6 (H) mm and fed by a 50 ¦¸ microstrip line. The proposed antenna has S ¡Ü -10 dB over 2.18-2.59 GHz, Bluetooth band, 3.098-5.15 GHz and 5.948-11.434 GHz, UWB band with WLAN band notch. The structure exhibits nearly omnidirectional radiation patterns, stable gain, and small group delay variation over the desired bands.
