The article considers the major operational circumstances of the design of sensors of electromagnetic fields, namely the difference in dielectric constant of the sensor body and its surrounding environment. Investigations have shown that the dielectric constant of the sensor substrate is critical to its sensitivity. The conditions close to the actual circumstances of operation are introduced as a result of measurement of significant errors. It is important to take into account the correcting coefficient for the dielectric constant of the material of the sensor body and its influence on the result of the measurement. It is why, by designing real measuring systems, the performance of the sensor application is important, in order to provide the best metrological characteristics with a wide range of measurements of projected invariant sensors. The results of the study show the necessity of observing the equality of dielectric permeability of the material of the sensor body and the environment surrounding it, and also fulfillment of the condition of selection of the angular dimensions of the sensor elements of the sensor from the range of 45° to 62° the greater the difference of dielectric permeability of the material of the sensor body and the medium, the greater the angular size.
