Abstract: This paper compares the efficiency of different ways to compute singular integrals for solving antenna problems using moment method matrix-vector equations. We use a biconical antenna as an example to assess the accuracy of different singular integral computation approaches. We also evaluate the computational complexity of the examined approaches and provide recommendations for the selection of the most optimal approach.

Keywords: antennas, numerical methods, method of moments, surface singular integrals, quadrature formulas, Duffy transformation, analytical expressions, computational complexity

Funding: The work was carried out with the financial support of the Ministry of Education and Science of Russia under project FEWM-2024-0005.
