“…To overcome the problems of electromagnetic interference, various printed monopole antennas with notched stop bands have been designed and investigated. Several design techniques proposed in open literature describe extremely wide band antennas with notched stop bands achieved by employing different modifications with slots on radiating patch or on ground plane such as split ring resonators (SRRs) [2]- [5], slot-type SRR [6] and combinations of them. This paper describes the design of an extremely wideband printed monopole antenna with dual notched stop bands by loading complementary co-directional SRRs on radiating patch with microstrip feed line is presented.…”

ABSTRACT:This paper proposes a design of an extremely wideband printed monopole antenna with dual notched stop bands for worldwide interoperability for microwave access (WiMAX) and wireless local area networks (WLAN). The individual notch frequencies are controlled by the individual split ring resonators (SRRs) and central notch frequency is determined by the individual SRRs physical dimensions. Predicted extremely wide impedance bandwidth of antenna is 2.67-22 GHz, for VSWR < 2 with two notched stop bands 3.36-4.10 GHz and 5.15-6.20 GHz, for VSWR > 2 is achieved for rejecting WiMAX (3.3-3.69 GHz) and GHz) band signals. Significant gain reduction over the notched stop bands and nearly omnidirectional radiation patterns over operating frequencies is also analysed. This paper describes the design of an extremely wideband printed monopole antenna with dual notched stop bands by loading complementary co-directional SRRs on radiating patch with microstrip feed line is presented. The wideband performance is achieved by modifying ground plane structure in respect of beveling edges and inserting square slot on it. By adjusting the dimensions and locations of the square slot and beveled edges, an enhanced impedance bandwidth is achieved. The stop band for WIMAX and WLAN is achieved by inserting complementary co-directional SRR in the radiating patch. By adjusting the size and location of the SRRs, the central notched stop band frequency can be controlled. The wideband performance is achieved by modifying ground plane structure in respect of beveling edges and inserting square slot on it. By adjusting the dimensions and locations of the square slot and beveled edges, an enhanced impedance bandwidth is achieved. The simulation of the proposed structure is carried out by using a commercially available software package CST Microwave Studio [7]. Fig. 1 shows a schematic diagram of the proposed extremely wideband printed monopole antenna with loading of SRRs. The antenna is printed on a glass epoxy FR-4 dielectric substrate with relative permittivity (ε r ) of 4.4, thickness of 1.6 mm, and loss tangent (tanδ) of 0.02. The radiating element and microstrip feed line of width 'W f ' are printed on the top side of the substrate and modified partial ground on bottom side to achieve 50 ohm characteristic impedance.
