“…Many band-notched antenna designs are achieved by cutting slots in the radiator [2,3]. To microstrip-fed UWB antennas, the band-notched characteristics can also be implemented by adding a stepped impedance resonator (SIR) or a split ring resonator (SRR) on the feed line [4,5] or cutting slots in the ground plane [6]. When it comes to CPW-Fed UWB antennas, most of the band-notched characteristics are implemented by etching slots in the radiator [7].…”

Abstract-In this paper, a coplanar waveguide fed (CPW-Fed) ultrawideband (UWB) antenna with dual band-notched characteristics is proposed. Two symmetrical slots are etched from the ground plane to achieve the notched band at 5.5 GHz. The other notched band at 3.5 GHz is obtained by etching a split ring slot in the radiator. The simulation and measurement show that the proposed antenna achieves an impedance bandwidth of 3.1-10.6 GHz with VSWR < 2, except in the bands of 3.2-3.8 GHz and 4.8-6.2 GHz. A nearly omnidirectional radiation pattern and stable gain with variation less than 3 dB are also observed except in the two notched bands. Moreover, time-domain characteristics of the antenna are analyzed and discussed as well.

“…So it is necessary to design the UWB antenna with band notched characteristic with reduced complexity and cost. The band notch characteristics can be obtained through different slots in radiated patch [6], fed line [7], slots in ground [8], and also parasitic patch [9]. Also a notch can be obtained using a quasi-complementary split ring resonator (CSRR) in fed line [10][11][12][13][14][15][16] or EBG structure etching on patch/ground plane [17].…”

In this paper, CPW-Fed ultra wideband (UWB) planar monopole antenna (PMA) loaded by double elliptical split ring resonators (ESRRs) for double band-notch characteristics is introduced and examined. Two different ESRRs with different dimensions are printed in the antenna backside to notch two different frequencies. The ESRRs are also rotated and the corresponding return loss effect is examined. Different notch frequencies can be obtained by varying the ESRRs, dimensions. Two single SRRs are used to notch two frequencies instead of using dual SRR pairs. Two notch frequencies at 5.2 GHz and 6.9 GHz has been obtained to notch WLAN and C-band wireless applications, respectively. A directive radiation pattern in E-plane and omnidirectional radiation patterns in the H-plane could be observed. Also the gain is suppressed in the notch frequencies. The group delay is nearly stable in the UWB frequency range, except at the notch frequencies, which is distorted sharply. So, the proposed antenna is a good candidate for the modern UWB systems. Finite element method FEM and finite integration technique FIT are used to simulate the proposed structures through the usage of Ansys HFSS and CST MWS. Very good agreement between both results has been obtained.

“…One approach is to perturb the radiating element shape [9][10][11]. Other approaches suggest including stubs [12], slots [13][14][15][16][17][18][19][20], or SRR resonators [21][22][23] to the radiating element. Lee et al [24] have chosen to perturb matching impedance and create an open circuit at the undesired frequency.…”

Abstract-In this paper, we present a new ultra wideband antenna design with band rejection for UWB applications. A CPW-fed circular patch radiates through a circular aperture, which ensures wideband impedance matching and stable omnidirectional pattern over an UWB frequency range, from 3 GHz to 10.6 GHz. In order to avoid interference with WLAN applications, at 5.8 GHz, the antenna is slightly modified to reject undesired band. A semi-circular slot ring is etched on the circular patch at the notch frequency, which creates an open circuit and avoids impedance matching and current propagation. A prototype was fabricated and measured, and the obtained experimental results agree with simulations and show an omnidirectional azimuth pattern over the entire bandwidth.
