An explicit and computationally efficient coupling impedance formula for the coupling between two perimeter ports on a perpendicular side of a right-angled isosceles triangular patch microstrip segment is derived. Based on coplanar circuit analysis an initial impedance formula is obtained in terms of a single and a double infinite series expression. Application of closed forms for the series reduces the single series to a closed form, and, the double series reduces to a single series. The new computationally efficient coupling formula is verified by comparison with simulation based on full wave analysis, and, practical measurement.
