“…185 With just two PIN 186 Badamchi et al, 187 have embedded slotted geometries into the radiating patch and then integrated PIN diodes for switching between single and dual notch performances. PIN diode switches are again embedded between U-shaped slots and parasitic patch in 188 and similarly, they are added between arc shaped slots in 189 for electronically switching the notch frequencies. Majid et al, 190 have used EBG structures connected with PIN diode switches to enable the reconfigurable operation.…”

Ultra‐wideband technology has experienced a rapid growth over the last decade for its contribution in different sectors of human society. Printed antennas are considered as preferred platform for implementing this technology because of its alluring characteristics like light weight, low cost, ease of fabrication, integration capability with other systems, etc. Antennas developed for ultra‐wideband applications are desired to have notch characteristics for avoiding interference with other existing radio communication systems. The techniques related to design and developments of printed band‐notched antennas are continuously upgraded for improving the antenna performance. In this article, a comprehensive review has been carried out on ultra‐wideband antennas with band notch characteristics proposed in around last decade. The band notched UWB antennas available in the literature have broadly been classified into five different categories based on their notch characteristics like single band‐notch, dual band‐notch, triple band‐notch, quad/multiple band‐notch, and reconfigurable/tunable band‐notch, respectively. This review exercise may be helpful for beginners working on ultra‐wideband band‐notched antennas and also such a review process is not available in the open literature to the best of author's knowledge.

“…There have been several studies on tunable or reconfigurable SRR by introducing two or more PIN diodes as switches or varactor diodes as a variable capacitors [10][11][12][13][14][15][16][17][18][19]. Using many PIN or varactor diodes complicates the manufacturing process by the need of DC biasing.…”

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.

Abstract-This paper proposes an ultrawideband (UWB) Vivaldi antenna with switchable and tunable band-notch characteristics. One stepped-impedance resonator (SIR), which has high quality factor Q and small size, is introduced to create band-notched characteristic with narrow notch band and high notch band edge selectivity. By loading two varactor diodes, a wide tunable notched band is achieved. The center frequency of notch band can tune from 3.1 GHz-6.8 GHz. In order to make the full use of UWB spectrum when there is on coexisting narrow-band applications, switchable band-notch characteristic is desired. Through rational parameters design, the center frequency of notched band is out of UWB range when the DC bias voltage of the varactor diode is 0 V. In this way, switchable band-notch characteristic is achieved.
