Annotation: This paper compares the efficiency of different ways to com-pute singular integrals for solving antenna problems using mo-ment method matrix-vector equations. We use a biconical an-tenna as an example to assess the accuracy of different singular integral computation approaches. We also evaluate the computa-tional complexity of the examined approaches and provide rec-ommendations for the selection of the most optimal approach.

Keywords: antennas, computational complexity, quadrature formulas, surface singular inte-grals, method of moments, numerical methods
