“…Very good agreement has been obtained between them. A 5.6 GHz and 5.4 GHz notch frequencies in the filter operating frequencies are obtained using ESRR without and with varactor loading, which covers WLAN band [21]. Figure 1 shows a schematic view of a CSRR formed with metallic strips of width, c, and radii r a and r ext forming the inner and outer rings, respectively with inter ring spacing, d. The splits on the inner and outer rings have gap dimensions g 1 and g 2 , respectively, lying diametrically opposite on the same axis.…”

The scope of this paper is to examine the effect of changing the structure of split ring resonator SRR from circular to an elliptical shape. The theoretical analysis of circular SRR (CSRR) is first examined and its results are compared with the simulated ones. Comparison between both configurations is also introduced. The new elliptical SRR (ESRR) can be adapted to operate in a multi-range of frequencies. The effect of gap position in ESRR resonant is also examined. When both gaps are moved but still aligned, the resonant frequency still the same. But when single gap is moved only the resonant frequency in changed to reach its maximum value when both gaps are in the same position. Frequency tunability can be offered by loading only a single varactor diode between the ESRR's metallic rings. The resonant frequency of the ESRR can be controlled by varying the capacitance of the varactor diode. Finite Element Method FEM is used to simulate the proposed structures using Ansys HFSS. A prototype of band notched coplanar waveguide filter loaded with single reconfigurable ESRR is fabricated and measured. A 0.5 pF single capacitor element is used instead of using varactor diode and the measured S 21 is compared with the simulated results. Very good agreement has been obtained between them. A 5.6 GHz and 5.4 GHz notch frequencies in the filter operating frequencies are obtained using ESRR without and with varactor loading, which covers WLAN band.

In this paper, a slot loaded ultra wideband monopole patch antenna with triple band‐notched characteristic has been presented. The antenna consists of rectangular patch with three modified inverted U‐shaped slots to create three notches at Wi‐MAX (3.3–3.6 GHz), C‐band (3.7–4.2 GHz), and WLAN (5.15–5.85 GHz) frequencies. Lumped‐element equivalent circuit model and current distribution curves have been used to explain the triple band‐rejection characteristics of the designed antenna. The proposed triple notch structure has been fabricated and tested against simulated data. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:138–142, 2017

“…To overcome this problem, UWB having band rejection characteristic is desirable. UWB antennas with band rejection characteristic have been proposed [4–18], mostly with one notch band [5, 6] for WLAN. For printed monopole antennas, the most familiar methods to achieve band‐notched function are etching U‐shaped slots [5, 12] on the metallic patch.…”

In this article, a printed plaque monopole antenna fed by a microstrip line for ultrawideband (UWB) width with triple notch band has been presented.The antenna is then modified to possess band rejection at the wireless local area network (5.1–5.8 GHz) by an inverted U‐shape slot or Π‐shape slot, or Λ–shape slot within the radiating patch. In addition, two half wavelength slots (U‐slot) are cut in the radiating patch to generate the first and third notch band in 3.25–3.75 GHz for WiMAX and 7.25–7.75 GHz for down link of X‐band satellite communication system. Surface current distributions and transmission line model are used to analyze the effect of these slots. The proposed antennas are simulated and fabricated. Radiation pattern shows good omnidirectional radiation patterns in the H‐plane and monopole like patterns in the E‐plane. The proposed antenna gain varies from 1.63 to 5.05 dB over the whole UWB region excluding at notch band. The design antenna has a compact size of 30 × 30 mm2. © 2012 Wiley Periodicals, Inc.
