Compact wilkinson power divider on multilayer org anic substrate

We present the design and development of a compact Wilkinson power divider on a multilayer organic Liquid Crystal Polymer (LCP) substrate. The experimental results demonstrate that the power divider has achieved a size reduction of 97.5% compares to conventional microstrip Wilkinson power divider design at a center frequency of 1.1 GHz. Based on a 15- dB input return-loss criterion, the power divider has a measured bandwidth from 0.95 to 1.25 GHz or 27.3% fractional bandwidth. The size of the power divider is 4.4 mm × 5.0 mm × 0.35 mm. This power divider achieves largest size reduction percentage reported to date in planar PCB technology.
