Coupling through dielectric‐covered slots is becoming a very important excitation mechanism for antennas and arrays in microwave and millimeter wave frequencies. The characteristics of these antennas can be analyzed by solving appropriate integral equations. A space domain method of moments applied for solving these equations may complicate the existing Sommerfeld integrals even more. In this paper a combination of analytical and numerical techniques has been developed which reduces the complexity of the integrals and improves efficiency and accuracy in their computation.
