A novel design of a dual-frequency unequal power divider is presented. The design is optimized using a genetic algorithm based method in order to satisfy several requirements at two given frequencies. The method considers realistic conditions, since it assumes lossy transmission lines and unmatched real or frequency-dependent complex loads. The method can be applied in a wide range of applicati...

A filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. This design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. The high isolation between output ports is obtained by combining the half mode substrate integrated wa...
