Abstract

In this paper, a miniaturized microstrip-based Bailey power divider is proposed by incorporating split ring resonators. New analytical design equations are derived for predefined power split ratios. To validate the proposed design methodology, two miniaturized dividers with 5:1 and 20:1 split ratios at 600 MHz are simulated, fabricated and measured. Simulated and measured results agree very well and show input port matching better than -15 dB and -20 dB at the design frequency, for the 5:1 and 20:1 dividers, respectively. The desired high split ratios are achieved with transmission parameters, S21 and S31, of -1.9 ± 0.1 dB and -8.9 ± 0.5 dB for the 5:1 divider, and -0.9 ± 0.1 dB and -13.9 ± 1.5 dB for the 20:1 divider, respectively. Furthermore, a size reduction better than 65% is achieved as compared to conventional footprints.
