Miniaturized structure and high directive gain performance of a patch antenna are primary requirements for modern wireless communication systems. In this paper, a novel design of dual band micro strip patch antenna with rectangular notch has been proposed for WLAN and WiMAX applications. For dual bands (3. 6 GHz and 5. 1GHz), proposed patch antenna shows quite satisfactory radiation and gain pe...

BACKGROUND Current literature for surgical deactivation of frontal migraine trigger points does not incorporate decompression of the supraorbital foramen or fascial bands at the supraorbital rim (frontal exit) as part of the surgical procedure. To evaluate this primary compression site for the supraorbital nerve, anatomical dissections were performed and a classification system was developed. ...

This paper presents an investigation of split ring resonator (SRR) parameters on a coaxial-fed monopole antenna. The adding of SRR slot can create a notch in the result of coaxial-fed monopole antenna design. Thus, this paper aims to investigate the effect of changes to the outer ring radius and slit cut width of the SRR slot. All antenna designs and simulations involved are drawn and simulated...

The microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. Recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. In this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. I...

A novel quadruple-notch UWB (ultrawideband) antenna for wireless applications is presented. The consists of a decagonal-shaped radiating part with Sierpinski square fractal slots up to iteration 3. ground truncated and loaded stubs slots. Each individual stub at the plane creates/controls particular notch band. Initially, designed help truncation plane. Miniaturization in this design achieved A...

Rugate designs for the realization of notch filters are well known in the literature. The required deposition of gradient index layers is difficult to manufacture. In our approach we apply the equivalent index theory to replace the gradient index profile of a notch filter design. We produce single and multiple notch filters with plasma ion-assisted deposition and broad-band optical monitoring. ...

A small antenna with single notch band at 3.5 GHz is designed for ultrawideband (UWB) communication applications. The fabricated antenna comprises a radiating monopole element and a perfectly conducting ground plane with a wide slot. To achieve a notch band at 3.5 GHz, a parasitic element has been inserted in the same plane of the substrate along with the radiating patch. Experimental results s...
