Evaluación de pérdidas de penetración en materiales mediante parámetros de potencia en la banda de 1 a 20 GHz para ondas milimétricas.

Abstract

The main objective of the present titration work was to evaluate the penetration losses in materials through power parameters of 1 to 20 GHz for millimeter waves. To this end, the state of the art analysis of the penetration losses in the range of 1 to 20 GHz was carried out, the specific characteristics of the equipment used for the various test scenarios were detailed, the physical and mechanical properties of the materials that are dry pine wood, wet pine wood, dry eucalyptus wood, wet eucalyptus wood, raw glass, tempered glass and concrete, measurements were made with 100 MHz jumps and a field distance of 50 cm was determined distant for the whole range of frequencies, the measurements were made without obstacle and with obstacle, where the power difference of these two signals allowed to calculate the insertion losses in each obstacle, the real part of the permittivity of each material was calculated, the which are within the theoretical values, it should be emphasized that the dry wood due to the drying techniques used, the permittivity varies between 2 and 5, while the permittivity of the wet wood is increased since the wood has water concentration whose permitivity is greater than the sample. The results obtained were satisfactory, in the frequency range of 1 to 14 GHz and 16 to 20 GHz the average penetration loss in the materials is 8.34 dB, but in the range of 15 to 16 GHz an average increase of 25.67 was obtained in dB, so it is concluded that at this range the losses in interiors are greater than the ones that should be considered for the planning of cellular networks.
