Coaxial Power Combiner with Eight Radial Coaxial Output Ports for Ka-Band Applications

This paper analyzes a K/Ka-Band coaxial power-combiner. The power combiner provides high power-combining efficiency over the entire waveguide bandwidth. The shape of the combiner is the radial-type and the output ports are designed to be coaxial lines. Losses experienced within the structure are remarkably minimal thanks to a Return Loss value of -27.8 dB at central frequency thereby ensuring optimal signal integrity. Then simulations were carried out by CST studio suite 2024.
