Abstract :
This paper suggests a novel cruciform substrate- integrated waveguide quadrature 3-dB hybrid, and shows the frequency characteristics of hybrids designed at various center frequencies using the H-plane planar circuit approach. As a result, relatively flat coupling properties are realized in a compact structure.
