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.
