In this paper we address the development of divider/combiners in waveguide technology for large number of ports. Radial waveguide dividers will be studied, starting from the S-parameters representing the N-port waveguide junction, and ending with the full-wave simulations. Two different designs in this technology are studied. The experimental evaluation will come from a prototype at Ku-band, fabricated and tested in order to validate the design.}, keywords = {antenna, array, corporate feed, linear polarization., SIW, stacked patch}, author = {R V Haro-Baez and J L Masa-Campos and J A Ruiz-Cruz and P Sanchez-Olivares and E V Carrera} }
