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

Abstract

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 < 2. Three Complementary Split Ring Resonators CSRRs are placed on the bow-tie antenna where each CSRR rejects one specific band. The CSRR1 rejects the IUT service band (8.025 - 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.
