چکیده

Antenna research has progressed significantly over the past decade, however to conduct any research, there needs to be one common resource: an antenna test range. This is because of the need to experiment on physical antennas. Numerically analyzing antennas is near impossible with the complex antennas that are prevalent today. Such systems that are offered commercially are very expensive and may not come packaged with features that are important. The primary goal of this project is to create an antenna test range without the expensive price tag of commercial systems. For this project, we utilize numerous advanced research tools and knowledge from electromagnetic theory, antenna measurement theory, RF/microwaves, electronics, communications, computer hardware, control theory, power analysis, mathematics, computational algorithms, and programming. Beyond the research required for this project, we will be working on developing a design, analyzing the design, modeling and simulating our system, programming, building, testing, budgeting, installing, and assessing on the management and design levels. The design level includes work on the system, hardware, electronics, and processor levels. This project is a continuation project extended the progress of the previous team. This is done by creating a completely new system partially common with the previous design. Utilizing aspects from multiple disciplines, the majority of the project was finished with the remainder becoming complete during the summer. Tying the two projects together is the governing computer, which allows for a full system test.

The Differential Phase Pattern of the CSU CHILL Radar Antenna

. The ~easurement of the differential propagation phase and copolar correlation coefficient are affected by the d1fferent1al phase pattern of the antenna system when operating in an alternate horizontal and vertical transmitting scheme. Direct phase pattern measurements of a large dish such as that of the CSU CHILL is difficult because of the need to obtain phase reference. A simple technique i...

Chronic urticaria: etiology and natural course in children.

BACKGROUND Chronic spontaneous urticaria (CSU) in childhood is infrequent, and information about the disease in children is limited. We attempted to investigate its etiologic factors, natural course, and predictors of prognosis. METHODS All children aged ≤ 18 years followed for CSU during an 8-year period were analyzed retrospectively, and the final outcomes were queried via a telephone inter...

Positive CD63 Basophil Activation Tests Are Common in Children with Chronic Spontaneous Urticaria and Linked to High Disease Activity.

BACKGROUND The basophil activation test (BAT) using CD63 expression is a sensitive and specific tool for the diagnostic workup of autoimmune chronic spontaneous urticaria (CSU). The definition of a positive BAT is directly dependent on the reference range and the cutoff values established in control populations. As of now, the pediatric reference range and cutoff values of the CD63 BAT remain t...

New Low Cost Printed Antenna CPW-Fed for Global Positioning System, Personal Communication System and Worldwide Interoperability for Microwave Access Band Applications (TECHNICAL NOTE)

This paper presents a new design of a CPW-Fed multi bands planar antenna. This antenna can be integrated easily with passive and active elements. The proposed antenna is suitable to operate for GPS, PCS and WiMAX bands. Its entire area is 52.3x52.6mm2 and is employed on an FR-4 epoxy substrate and fed by a 50 Ohm coplanar line. The antenna parameters have been analyzed and optimized by using AD...
