A High-Frequency/Power Ratio Wilkinson Power Divider Based on Identical/Non-Identical Multi-T-Sections With Short-Circuited Stubs

In this article, a systematic procedure is presented for the design of dual-band unequal-split Wilkinson power divider (WPD) with high frequency and division ratios. The methodology based on replacing impractical high-impedance transmission line in conventional cascaded T-section structures short-circuited stubs. proposed simple adopts distributed elements without reactive components to achieve large ratio. use stubs allows circuit miniaturization comparison counterpart open-stub techniques. Furthermore, ratio obtained through optimizing electrical physical parameters T-sections lines theory framework as demonstrated simulated measured prototype. To validate procedure, two WPD prototypes operating at 1/2.7 GHz 1/4.4 1:10 are measured. theoretical response, supported by electromagnetic simulations measurements, justifies concept.
