Abstract
We study the port-to-port coupling of leaky-wave metasurface (MTS) antennas comprising multiple feeds. An efficient Method of Moments (MoM) simulation tool is developed to analyze such antennas. The MTS and the feeders (coaxial probes) are described using local basis functions. The surface current on the MTS and on the probes are computed iteratively using the GMRES algorithm. The matrix-vector products at each iteration are accelerated with the FFT thanks to the regularity of the mesh. Once the surface currents are obtained, the coupling between the ports can be calculated.
