A fast full-wave analysis scheme of high-gain superstrate antennas

The performance of superstrate antenna is analyzed using a fast full-wave scheme, based on the Contour-FFT, which rapidly calculates the substrate-related interactions between macro basis functions (MBFs) in spectral domain. In this paradigm, the interaction between MBFs versus relative position is...

Description
Summary:The performance of superstrate antenna is analyzed using a fast full-wave scheme, based on the Contour-FFT, which rapidly calculates the substrate-related interactions between macro basis functions (MBFs) in spectral domain. In this paradigm, the interaction between MBFs versus relative position is tabulated first using C-FFT, then the interaction between printed elements on superstrate layer of the antenna are instantly obtained by interpolating the table, allowing a fast evaluation of superstrate antennas. As an example, a design of a 5×5 square patch superstrate antenna fed by a dipole is presented and the results are discussed.
