Abstract:
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,p ower 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 righthanded (RH) TLs. Finally,an X-band series feed network is designed and fabricated as an example. The simulated and measured results indicate that the present design can achieve even amplitude and phase distributions among different output ports in the range of 8.8-9.6 GHz. And it has other advantages such as a compact size of 350mm×50mm and good return loss which is higher than 22 dB in the operation frequency.
