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.
