Hybrid finite element/boundary element analysis of a stripline notch array

The results of a two-dimensional finite-element/boundary-element time-harmonic analysis of an eight-element stripline notch phased array are presented. The hybrid finite-element/boundary-element method can be used for both near and far-field radiation and scattering analysis. The boundary-element method is used for the exterior far-field region, and the finite-element method is used for the near-field antenna/scatterer region. Predictions are given and compared with measured results of array-element pattern, gain vs. frequency, and array scanned pattern.<
