MEASUREMENT TECHNIQUE OF REFLECTIONS COEFFICIENTOF RADIO WAVES BY SHEET MATERIALS
Methods for measuring the reflection coefficient of nonionized electromagnetic radiation from sheet materials are considered. Horn antennas with square apertureswere used for measurements. The maximum dimensions of the irradiation spot are determined dependingon the distance to the irradiating horn antenna for different frequency ranges. Two methods ofmeasuring the reflection coefficient of radio waves from sheet materials are described. A measuringinstallation was made.
