Improving the performance of the 3-dB microstrip hybrid-ring based power dividers

The results of theoretical and experimental studies of 3-dB power dividers in integrated microstrip-line based planar technology are shown and concluded. Presented work focuses on the application of well-known hybrid ring structure in hybrid power dividers/combiners. Modified version of the original structure is proposed to achieve enhanced performance of in-phase power divider around mid-band frequency. The achievements of this study demonstrate the accuracy of applied simulation tools as well as potential utility of analysed structures for the construction of quality planar integrated circuits such as balanced components and multielement feeders.
