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 - 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.

Summary

Chaibo et al 272

2002 by the Federal Communications Commission [1]. The UWB technology can cover multi standards applications, offering several advantages in terms of high data transmission rate with low power consumption, low cost and low complexity. Different types of UWB antenna topologies with single, dual, triple or quadruple band notched characteristics have been designed and reported in the literature [2]-[10]. Most common among these topologies-related fabricationmethods are etching techniques of various slots with different shapes (U-Shaped, C-Shaped, nested C-shaped, L-Shaped, Split Ring Resonators-SRR, Complementary SRR...). The bow-tie antenna is considered as a planar biconical antenna version, it has a symmetric structure for which the currents are mostly focused on the edges [16] We have chosen this type of antenna because of its attractive radiation characteristics, its compactness and its lightness. Note that all simulations presented in this work are conducted using Ansoft High Frequency Structure Simulator (HFSS 17.0) simulator
