Abstract :
A spatial power combining circuit that forms a single resonant structure from many active devices is introduced. A large-signal analysis of this power combiner was performed. Based on these results, a two- and a nine-MESFET two-dimensional combiner driving two- and nine-patch antenna elements, respectively, were designed and fabricated. Measured results are presented. An effective radiated power of 6.06 W at 7.33 GHz was obtained from the nine-MESFET combiner.<>
