NAVSYS has developed a new Digital Antenna Element design for integration with a Controlled Reception Pattern Antenna (CRPA) which offers significant advantages over conventional Digital Antenna Electronics for high integrity GPS applications such as the Joint Precision Approach and Landing System (JPALS). Instead of performing spatial processing within the Digital Antenna Electronics, the Digital Antenna Elements each output the raw sampled digital data from each of the CRPA antenna raw sampled digital data from each of the CRPA antenna eleme ....etc

1.INTRODUCTION
Vehicular land transportation has become an indispensable and
necessary element of contemporary society activities. However, the vehicle
transportation environment has been facing severe situations with increasing
number of accidents and congestions in many metropolitan areas and
highways worldwide. This necessitates the adaptation of intelligent
transportation system (ITS) that could improve vehicle driving environment
with respect to safety, efficiency, and information availability. This demand ....etc

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

Design and analysis with low side lobes of Fractal Linear Array Antenna
Abstract
In this paper, the fractal concept is used in the linear array antenna design to obtain multiband operation and reduced size. MATLAB programming language version 7.0.1 is used to simulate the fractal linear array antenna and their radiation pattern. Fractal Cantor linear array antenna of array pattern of 101 has been designed at a frequency of 2700 MHz with uniform and non uniform amplitude distribution. The performance of this array ha ....etc

DEVELOPMENT OF HIGH PRECISION SLOTTED ARRAY WAVE GUIDE ANTENNA FOR AEROSPACE APPLICATION
INTRODUCTION:
Missiles are guided towards the target through the seeker. Mono pulse antennas give the location of target. Thus tracking of the target depends upon the performance of the antennae.
The slotted wave guide array antenna offer various advantages like planar configuration and compact structure.
The performance of these antennae depends upon various parameters like slot ....etc

Abstract

The rapidly increasing demand for PCS has provided the impetus to design adaptive antenna arrays to improve spectral efficiency and enhance system capacity. With increasing data rate in some PCS application like DECT( Digital European Cordless Telecommunications), higher BER would degrade the system performance further. An adaptive antenna array testbed using 12 elements was built to evaluate its performance on high data rate mobile communications in an indoor environment for DECT applications. The simultaneous data sampling rate ....etc
