Experimental Verification of the Algorithm for Positioning at a Required Point of Maximum Electric Field Strength

This paper examines the prototype of a focused antenna array. Using a prototype, experimental verification of theoretical results describing the shift of the peak value of the electric field intensity regarding to the point of common mode addition of waves was carried out. The experimental results coincided with the theoretical ones with an error of no more than $5 \%$. The standard deviation between the theoretical and experimental dependencies confirmed the reliability of the theoretical results. The work also carried out experimental testing of the algorithm for positioning the maximum amplitude of the electric field strength. The algorithm for positioning the peak value of the electric field intensity gave complete coincidence with the theoretically calculated position of the peak value of the electric field strength. The discrepancy between the theoretical and experimental dependences is insignificant, which is confirmed by the small value of the standard deviation. The work also provides a description of the components of the developed prototype of a focused antenna array. Photos of the prototype and the measurement process are provided.
