Short summary
A substrate integrated waveguide (SIW) replacing a costly rectangular waveguide is used with transverse slots edged in the top cover of the SIW as effective leaky-wave antenna with radiation direction parallel to the antenna (end-fire) until to 60 degree upwards by frequency scanning. The efficiency is optimized by a procedure leading to a 99 per cent efficiency at end-fire. With special feeding and power dividing circuits, a two-branch antenna could be designed with a further improved gain.
