Based on Composite Right/Left-Handed (CRLH) Transmission Line (TL), a novel series feed network for microstrip arrays is proposed and its theoretical analysis and experimental results are presented. In the present structure, power dividers and open-ended stubs are employed to even the amplitude distributions among different output ports, while CRLH TLs and short meandering lines are used to compensate the phase delay caused by the different lengths of Right-Handed (RH) TLs. Finally, an X-band series feed network is designed and fabricated as an example.
