In recent years a number of researchers have proposed novel techniques for fabricating rectangular waveguide using

microwave integrated circuit techniques. These so-called substrate integrated guides have been fabricated using

multilayer LTCC, multi- and single-layer microwave laminates and photoimageable thick films. All of

these structures result in dielectric filled rectangular waveguide and as such have a width reduction of 1/square root of the relative permittivity over conventional waveguide. Furthermore, by their very nature they are easily integrated with planar transmission lines and circuits, allowing hybrid waveguide/microstrip systems to be fabricated on a single substrate. Several researchers have investigated slot antennas and arrays in substrate-integrated guide. In this paper we show a slot antenna in a folded substrate-integrated waveguide. These waveguides have half the width of the other types of substrate-integrated waveguide. As such the present structure allows arrays of slot antennas to be more highly integrated.
