Miniaturization of Wilkinson Power Divider Using Zigzag Combination of Microstrip and CPW Lines
This paper introduces a composite microstrip-CPW transmission line that owns a unique feature of dual signal-path. The dispersive characteristic impedance of the composite line is revealed here and a design example of a miniature 2-way power divider is demonstrated by using the zigzag lines. A size reduction factor of 87% and a bandwidth of 57.4% are achieved and validated with experiment.
