Über dieses Buch

This book is a pioneering exploration of a new form of high-frequency

attenuation chamber that has the potential to revolutionize antenna measurement

techniques. The authors present an innovative concept that leverages the

classical principle of changing the polarization of radio waves, eliminating

the need for traditional non-reflection chambers. By analyzing experimental

results and searching for the optimal shape and composition of a depolarization

panel, this monograph provides valuable insights into creating a non-reflective

environment for accurately measuring the directional properties of antennas.

The book delves into the methodology of frequency analysis, optimization of the

depolarization panel, and the creation of a measuring workplace using this

panel. It highlights the crucial attenuation phenomenon of suppressing

cross-polarization coupling between transmitting and receiving antennas,

enabling antenna measurements in any laboratory environment. With its promising

results and practical applications in antenna technology, this publication

offers a compelling and cutting-edge approach to antenna measurement that will

captivate researchers, engineers, and professionals in the field.

1. Introduction
Abstract
The high-frequency anechoic chamber is an essential piece of equipment in the aerospace development laboratory environment. Its design creates an almost ideal measurement environment for RF technology.
Martin Krchňák, Marek Češkovič, Pavol Kurdel, Anton Panda
2. Anechoic Chambers for Radio Waves
Abstract
This chapter deals with the current state of the art in the field of radio-frequency anechoic chambers used in domestic and foreign laboratories.
Martin Krchňák, Marek Češkovič, Pavol Kurdel, Anton Panda
3. Depolarization of a Wave on a Conducting Grid
Abstract
The first chapter presents the generally known classical non-reflective chambers used in the HF technique. In terms of practical use for various measurements of HF devices, they are fully compliant in terms of dimensions, shape, or power used.
Martin Krchňák, Marek Češkovič, Pavol Kurdel, Anton Panda
4. Standard Methods for Analyzing Antenna Parameters
Abstract
This chapter describes methods for measuring selected antenna parameters. These are mainly methods for measuring impedance parameters, measuring antenna radiation patterns and measuring gain. Measurements in antenna technology require a wide range of different measurement methods and instrumentation. Typically, these range from simple measurements such as impedance matching and transmission measurements, to high-resolution radiation pattern measurements and long-range pulse response measurements. Many antenna measurements require shielded anechoic chambers, reflectors, test antennas with known parameters, handling equipment and cost-effective software.

5. Technical Equipment of the Antenna Laboratory
Abstract
The successful completion of the work requires sophisticated technical equipment. The measurements on which all the work is based are in the range of radio waves with frequencies below 10 GHz. Without the necessary equipment, it would be impossible to solve the work practically and to carry out the necessary experiments. The technical equipment is expensive and emphasis is placed on accuracy and quality of workmanship. The chapter contains a detailed description of the basic characteristics of the elements of the Aircraft Systems Laboratory. The description of the laboratory is based on a series of experiments designed for this purpose. Such a description will be the basis for future experiments, as it will provide information on the properties of the measured elements.
Martin Krchňák, Marek Češkovič, Pavol Kurdel, Anton Panda
6. The Optimalization of the Depolarization Panel
Abstract
In the second chapter of the monograph, the theoretical principle of polarization and reflection of an electromagnetic wave on a wire grid and a sheet is explained in detail. Based on the theoretical assumptions, an experimental depolarization panel has been proposed in the development process.
Martin Krchňák, Marek Češkovič, Pavol Kurdel, Anton Panda
7. Optimization Layout Elements Measurement
Abstract
This chapter is dedicated to one of the practical applications of the depolarization panel. The main intended use of the depolarization panel is to measure the radiation characteristics of antennas. The previous chapter provided important knowledge about the properties of the depolarization panel itself. Thanks to this knowledge, such as working frequency and suitable panel shape, it was possible to design a basic methodology for measuring radiation characteristics using a depolarization panel.
Martin Krchňák, Marek Češkovič, Pavol Kurdel, Anton Panda
8. Exploitation Methods in Antenna Technology
Abstract
After the implementation of the depolarization panel, the optimization of the attenuation depolarization chamber and the design of a new method for measuring the radiation characteristics of antennas, the actual measurement of the antenna characteristics was carried out.
Martin Krchňák, Marek Češkovič, Pavol Kurdel, Anton Panda
9. Conclusion
Abstract
Since the changes in former Eastern Europe in 1989 and 1990, new trends in regulating production processes and evaluating machines, production processes, and gauges have now impacted our society.
