A CPW-Fed Diamond Shaped UWB Monopole Antenna with Dual Band-Notched Characteristic
Keywords:UWB microstrip antenna, diamond shape, monopole antenna
A CPW-fed diamond-shaped UWB monopole antenna with dual band-notched characteristics at WiMAX (3.3-3.7 GHz) and WLAN (5.15-5.825 GHz) band is proposed. The proposed antenna consists of a CPW-fed diamond-shaped monopole radiator, two vertically extended ground planes around the radiator, rotated C-shaped and inverted L-shaped slits. The antenna is fabricated on 1.6 mm thick FR4 material with an overall size of 25 × 23 mm2 and offers an ultra-wide bandwidth from 2.49-12.8 GHz with dual band-notched characteristics at the WiMAX (3.1-3.8 GHz) and WLAN (4.9-5.8 GHz) bands without affecting the radiation performance of the antenna. Dual band notched characteristics at 3.1-3.8 GHz (WiMAX) and 4.9-5.8 GHz (WLAN) are achieved due to inserting an inverted L-shaped slit on the ground plane and a rotated C-shaped slit on the radiating monopole, respectively. Thus, the antenna is suitable to be integrated into the portable devices without EMI interference at WiMAX and WLAN bands.
