An Ultra-wideband Power Divider with High Isolation Using Tapered Lines

This research presents an ultra-wideband power divider crafted through the integration of bending arcs and tapered lines. Four sections of these components, accompanied by resistors, enhance isolation. The power divider demonstrates favorable return loss of −10 dB from 3 GHz to 14 GHz. Output return loss and isolation also exceed −10 dB across the entire 3 GHz to 14 GHz frequency spectrum. ADS software facilitates simulation on a 0.8mm thick Rogers 5880 substrate.
