A Novel Bow-Tie Antenna with Triple Band-Notched Characteristics for UWB Applications

摘要

This?paper?presents the design of a compact bow-tie antenna with triple band notched characteristics for UWB applications. The proposed antenna can operate from 3.1 to 10.6?GHz with VSWR??-?8.4 GHz) centered at 8.1 GHz,?the CSRR2 rejects the WLAN band (5.15?-?5.85 GHz) centered at 5.6 GHz, and the CSRR3 rejects the band (4.10?-?4.47?GHz) centered at 4.32 GHz. Compared with recent design, this antenna is more compact, and presents?better?simulation results of its characteristics. Our newly designed antenna is a potential candidate for application in UWB communication systems.
