Planar Array Antenna – Implementation


Structure Of planar array antenna

The fabrication and assembly of the antenna array with separated feed network using the air gap technique is described here.

The basic structure of the proposed antenna is constructed using multiple 2x2 sub-array modules with its “H shape printed feed line

The antenna is fed by a 50Ohm coaxial probe. The size of each patch is 16mm x 11.15mm and their inter-element spacing is ....etc

Power over Ethernet (PoE) is a revolutionary technology that extends the already ultra-broad functionality of Ethernet by supplying reliable DC power over the same twisted-pair cable that currently carries Ethernet data.

PoE, modeled after the technology used by the telecommunications industry to supply reliable power to telephones, enables lifeline quality power for IP telephones (VoIP) as well as many other low power Ethernet network devices like wireless access points (WAP) and security cameras.

When locating access points, system des ....etc

Introduction
I/O-efficient graph algorithms have received considerable attention lately because massive graphs arise naturally in many applications. Recent web crawls, for example, produce graphs of on the order of 200 million nodes and 2 billion edges. Recent work in web modeling uses depth-first search, breadth-first search, shortest paths, and connected components as primitive operations for investigating the structure of the web.

Massive graphs are also often manipulated in Geographic Information Systems (GIS), where many fundamental pr ....etc

Abstract
We present a novel multi-view stereo method designed
for image-based rendering that generates piecewise planar
depth maps from an unordered collection of photographs.
First a discrete set of 3D plane candidates are computed
based on a sparse point cloud of the scene (recovered by
structure from motion) and sparse 3D line segments reconstructed
from multiple views. Next, evidence is accumulated
for each plane using 3D point and line incidence and
photo-consistency cues. Finally, a piecewise planar depth
map is recove ....etc

MULTI-SLM HOLOGRAPHIC DISPLAY SYSTEM WITH

PLANARCONFIGURATION


INTRODUCTION



-One way to enhance the 3D viewing comfort is to increase the hologram size (i.e. SLM size).
-Therefore, we propose and implement a multi-SLM holographic display system.
-The holographic display consists of six high-definition phase-only SLMs which are tiled in three by two fashion. After aligning them by using some optical elements and high precision stages we generate a la ....etc

different antennas have been developed and investigated for RKE (Remote Keyless Entry) and related automotive applications. These antennas include small printed-on-dielectric passive and active, printed-on glass, and whip-splitter types. Key antenna parameters-including size, performance, antenna shape-are proposed, investigated,The characteristics of small antennas taking into account the often significant effect of the cable length and direction position have also been investigated and are presented; solutions are also presented that eliminat ....etc

Ethernet passive optical networks (EPON) are an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office (CO) and a customer site. EPONs build on the International Telecommunications Union (ITU) standard G.983 for asynchronous transfer mode PONs (APON) and seek to bring to life the dream of a full-services access network (FSAN) that delivers converged data, video, and voice over a single optical access system.
The communications industry is on the cusp of a revolut ....etc
