Design of Dual High Band-Notch UWB Antenna Based on CSRR and Parasitic Arms

In this paper, a novel compact, low profile, low cost, microstrip fed line with single and double band-notch characteristics ultra wideband (UWB) patch antenna is presented. The proposed antenna satisfying UWB operation from 3 GHz - 11 GHz with two notches and have maximum gain 4.9 dB. The first band-notch is designed to reduce the electromagnetic interference in WiMAX frequency band (3.8 GHz), while the second band notch of WLAN IEEE 802.1a (5.35 GHz). By inserting seven different size arms of a single parasitic split ring resonator (SPSRR) band notch in the range of 3.3501-4.5857 GHz is obtained. Furthermore, the second band notch around from 5.1 - 5.6 GHz for WLAN is obtained by etching circular complementary split ring resonator (CSRR) near the microstrip feed line. A very high agreement between simulation and experimental results is achieved. The proposed antenna can be considered as a good candidate for UWB communication applications with very low electromagnetic interference.
