Abstract

The iterative MoM-PO approach is utilized to calculate the radiation pattern of antenna around arbitrarily shaped structure. The structure is composed of Non-uniform rational B-spline (NURBS) surfaces. The hybrid MoM-PO approach is implemented by iterating the voltage matrix of the MoM region. A more rigorous formula for the scattered field of the PO region is presented in case that the antenna is located close to the structure. The stationary phase method (SPM) is applied for the integral of the induced current in the PO region. Results obtained from this method and from iterative MoM-PO approach based on triangle facet model agree well.
