Abstract:

The thesis introduces the technology of radial combining.Then it analyses the electromagnetic of radial waveguide,and puts forward a new power combining structure.It designs the structure of Ku band 4-port power combining based on radial combining,and  simulates  the speciality of surface electricity distributing、electricity  energy density、insertion loss、standing wave by CST.The simulational result illuminates that this power combining,which has fine characteristics,applys for the demand of large output power and breaks through the technology bottleneck of engineering application.

Key words: microwave;radial combining;Ku-band;spatial power-combining
