Generalized Admittance Matrix Method for Fast Full-Wave Analysis of Integrated Lens Antennas

07 Apr 2014

This paper presents an efficient technique for full-wave analysis of dielectric lenses with integrated feeding. The feeding section is analysed with a higher-order 3D-MoM algorithm, while the rotationally symmetric lens is analysed with a higher-order BoR-MoM. Each method allows the extraction of a generalized admittance matrix that fully characterizes the region in question. The individual matrices are finally combined to form the overall admittance matrix, which may subsequently be used to compute all desired quantities (scattering parameters or fields). The method is well-suited for optimization, since a change of the geometry inside an isolated region does not require recomputation of other admittance matrices. The proposed method provides a full-wave solution of typical integrated lens antennas in 1-2 minutes.
