Abstract— A simple and compact ultra-wideband (UWB) antenna integrated with dual band-notched and desirable gain characteristics is presented in this article. The proposed antenna consists of a rectangular-shaped radiator with a partial ground plane and fed by a 50 Ω microstrip line. By inserting two altered H-shaped slots on the proposed radiator, dual band-notch are created to eliminate the w...

Mammalian Notch receptors contain 29-36 epidermal growth factor (EGF)-like repeats that may be modified by protein O-fucosyltransferase 1 (Pofut1), an essential component of the canonical Notch signaling pathway. The Drosophila orthologue Ofut1 is proposed to function as both a chaperone required for stable cell surface expression of Notch and a protein O-fucosyltransferase. Here we investigate...

A novel method for optical generation of ultra-wideband signals with a reconfigurable spectral notch-band is proposed. In the proposed system, ultra-wideband signals are generated in the optical domain and an optical tunable delay line is deployed to introduce a notch-band to the spectral profile of the generated ultra-wideband signals, which can effectively avoid the signal interference betwee...

A novel modified printed monopole antenna with variable frequency band-notch characteristic for ultra-wideband (UWB) applications is presented. The proposed antenna consists of a truncated ground plane and a radiating patch with two tapered steps. To generate a notch band at 5–6GHz with good level of band-notch a new T-shaped parasitic element placed on the back layer of the substrate along wit...

Therefore, is crucial component transceivers which can support multiple services one device. This paper presents design dual-band at 2.4 GHz and 3.5 for WLAN WiMAX applications. Firstly, wideband designed center frequency 3 based on qua...

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...

In this paper, a novel design method for a dual-band bandpass filter (BPF) with arbitrary controllable bandwidths based on a simple frequency mapping function is proposed and its analytical design equations are also derived. The circuit conversion techniques are employed for implementation with distributed transmission line. To validate the proposed dual-band BPF with controllable bandwidths, a...

Abstract: The purpose of IIR notch filter is to remove Narrow Band Interference signal while leaving Broad Band Signal unchanged in communication system. This research paper presents a method for design of fixed notch filter at center frequency FO (90MHZ). We calculate two parametric values like pass band ripple &stop band attenuation by using mathematical modeling. For this purpose we have sel...
