Low Profile, Frequency Scanned Weather Radar Waveguide Feed Manifold

In this paper, a novel approach to achieving a low profile, low loss feed manifold for center-fed frequency scanned radar systems has been presented. Inclusion of a reactive buffering region, allowing independent control of the slot in each waveguide, has been shown to increase degrees of freedom in design efforts and decrease mechanical tolerance requirements, thus permitting the use of standard low cost machining practices
