Summary:
The thin-film Ultra-Wideband (UWB) antenna fed by Coplanar Waveguide (CPW) with triple band-notched characteristics is presented in this paper. This proposed antenna has concise dimensions of 34.5ﾃ・7.6 mm2 and is fabricated on flexible thin-film Mylar Polyester. In addition, the thickness and dielectric constant of polyester is 0.3 mm. and 3.2, respectively. The prototype antenna consists of fork-like tuning stub fed by CPW and rectangular slot. Moreover, two strait slots and U-shape slot is added on the top ground plane to accomplish triple band-notched at frequency range of 3.3 - 3.7 GHz (WiMAX), 5.1 - 5.8 GHz (WLAN), and 7.25 - 7.75 GHz (X-Band downlink). For measurements of antenna, the operating frequncy is 2.8 - 13.5 GHz which has three notched-frequency at 3.5, 5.5, and 7.5 GHz. Furthermore, the measured gain is average 3.6 dBi entire bandwidth except notched frequencies which decrease extremely lower than 0 dBi. As the results of measurement, the prototype antenna can appropriately attain triple notched-band for WLAN, WiMAX, and X-Band Communication and is also properly used in UWB equiptment and system.
