  • Abstract
    Numerical solutions are obtained for the problem of radiation from an infinite array of rectangular waveguides, each of which is loaded with iris at the array aperture. It is shown that the introduction of aperture irises can remove a radiation null in the active element pattern and significantly improve the array performance over a wide frequency band.
