HFSS design for radial combiners

Dear Friends,

I am currently working on Microwave Radial Power Combiner. My aim is to design a microstrip based structure so that it will be small and can also handle bands like L,S, Ka & Ku. I am using HFSS for my simulation and i am abeginner in it also. I searched many journals for the design but coudnt get a proper one. Any body mastering in this area kindly help me by sending a sample model on microstrip based radial power combiners.
Thank You all....and I love this blog..
