Abstract:

This paper presents the design of a band-notched simple iterative compact pentagonal fractal antenna. The antenna dimensions are W × L = 32 mm × 22 mm. The fractal radiating patch is placed on the front side of the FR 4 substrate material. The proposed fractal antenna geometry consists of a pentagon shape with three simple iterations of scale factor 0.62. The band-notched filter has been achieved by itching the pentagon shape as a parasitic patch on the back side of the substrate. The impedance bandwidth and reflection coefficient of the antenna are improved with the design of three iterations

AbstractA compact ultra-wideband (UWB) monopole antenna with reconfigurable band-notch characteristics is demonstrated in this paper. It is comprised of a modified rectangular patch and a defected ground plane. The band-notch property in the WiMAX and WLAN bands is achieved by etching an open-ended slot on the radiating patch and an inverted U-shaped slot on the ground plane, respectively. To obtain the reconfigurable band-notch performance, two PIN diodes are inserted in the slots, and then the notch-band can be switched by changing the states of the PIN diodes.

Abstract:

In this paper, an ultra-wideband (UWB) filter with a notch band using T-shaped step impedance resonator loaded with cross-shaped open stubs has been presented. The notch band is formed by utilizing intrinsic zero. The characteristics of the new quad-mode resonator have been analyzed using odd-even mode analysis method. It can be shown that it is the intrinsic zero that generates the notch band. In addition, wide tunable notch band form 5–9.3 GHz can be achieved. A UWB filter with a notch band centered at 6.25 GHz using the proposed quad-mode resonator has been designed, fabricated, and tested.

The notion of a quality criterion for non-tunable band-stop filters is introduced, and on the basis of it a comparison of filters with different designs is performed. The quality criterion takes into account the electrical characteristics of the filter and its dimensions, including the volume, the central frequency of the notch band, the level of total losses in the passbands, the width of the notch band by the level of total losses, the width of the notch band by attenuation level. Thus, it allows you to compare the quality of design and manufacture of passive notch filters of various types.

Measurement results show that the notch bands could switch between 4.2 GHz and 5.8 GHz when the state of varactors is fixed, and the ranges of tuning are 4.2–4.8 GHz and 5.8–6

Therefore, this resonator can be modeled as a shunt circuit to ground, with the R, L and C elements connected in series.

Abstract:

A novel ultra-wideband(UWB) bandpass filter with dual notch-bands and wide stop-band is proposed. The designed UWB BPF is cascading a coupled simplified composite right-left-handed (SCRLH) resonator and a ring slot resonator (RSR). The SCRLH resonator creates two different notch-bands. And the RSR unit suppresses the higher-order harmonics at the upper stop-band. The UWB BPF demonstrated good insertion/return losses and out-of-band rejections in simulation.

Abstract:

The present work shows a planar compact ultra-wideband (UWB) monopole antenna with controllable dualband-notch frequencies at 3.3 GHz for WiMAX and 5 GHz for WLAN. In the proposed antenna, the lower notchband (at a frequency of 3.3 GHz) is made by cutting a thin horizontal strip on top of the radiating patch. The uppernotch band (at a frequency of 5 GHz) is made by putting two narrow parasitic strips in the shape of an “I” oneither side of the radiating patch. The incorporation of three varactor diodes between the radiating patch and three metallic strips provides the flexibility of adjusting

The EBG structure has a bandgap centered at 6.69 GHz which is almost 38% lower compared with the conventional uniplanar EBG of same dimensions. A one-dimensional EBG structure coupled with a microstrip line provides a narrow bandgap, which is used in obtaining a notch in the UWB filter. Single notch UWB filters with variations in the placement of EBG are fabricated producing a notch centered at 5.19 GHz (wireless local area network (WLAN
