Definition

The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM ....etc

Design and development of X-band micro strip patch antenna

Introduction

In high-performance aircraft, spacecraft, satellite and missile applications, where size, weight, cost, performance, ease of installation, and aerodynamic profiles are constraints, low profile antennas may be required. These antennas should have low profile, conformable to planar and non-planar surfaces, simple and inexpensive to manufacture using modern printed-circuit technology, mechanically robust when mounted on rigid surfaces, compatible with MMIC designs, and w ....etc

ABSTRACT

This report introduces a novel examplar-based inpainting algorithm through investigating the sparsity of natural image patches. Two novel concepts of sparsity at the patch level are proposed for modeling the patch priority and patch representation, which are two crucial steps for patch propagation in the examplar-based inpainting approach. First, patch structure sparsity is designed to measure the confidence of a patch located at the image structure (e.g., the edge or corner) by the sparseness of its nonzero similarities to ....etc

Abstract
This paper present the design of an S-band circular microstrip patch antenna using a conventional coaxial probe feed technique. The antenna is designed to function within the frequency range of 2.0 GHz - 2.5 GHz, S-band. The antenna exhibited a return loss of -16dB and a directivity of 6.07dB. The microstrip patch antenna is designed on FR4 epoxy substrate and is to be feed with a 50 coaxial cable. The design of the antenna is done using MATLAB software and SonnetLite software for the electromagnetic simula ....etc

Abstract
Two major objectives are concerned in this paper. On one hand, a multiplicity of typical methodologies available for achieving dual-frequency operation for microstrip patch antennas are summarized and classified into three categories, based on their intrinsic mechanisms. On the other hand, by employing the dual-frequency solutions, microstrip patch antennas are applied to the mobile handsets of the third-generation IMT-2000 system. Two novel microstrip patch antennas with broadband property and miniaturized size have been proposed a ....etc

dual orthogonal fed microstrip patch antenna

Abstract

A broadband dual-feed dual-polarized microstrip antenna with low cross polarization and high isolation is presented. The dualorthogonal linearly polarized mode is excited by two different feed mechanisms from a single circular radiating patch. One of the two modes is excited by a pair of L-shaped probes with a 180 phase differences, and the other is excited by an H-shaped aperture. The proposed design has a very simple antenna structure with a wide input impedance bandwidth (23.25% for Po ....etc
