This article uses the conformal mapping technique (CMT) to study the irregular pentagonal waveguide (IPWG). This technique is applied to map the IPWG into a simple rectangular one. The lowest cutoff frequency $(f_{c})$ of this waveguide is calculated from its wave equation in the transformed domain using the Galerkin method. The relation between $k$ and $\beta$ of the pentagonal waveguide is also studied with the help of this technique. Numerical 3D electromagnetic simulator (HFSS) is used to validate the results.
