A novel UWB Wilkinson power divider

Abstract

A novel UWB power divider formed by installing one overlapped butterfly radial stub on each branch is proposed. Such structure makes branch line shorter and circuit's size smaller compares to power divider with single radial stub. It's also achieved a compact size of 18 mm by 16 mm. The simulation and measurement results of the UWB power divider are presented and shown good agreement.
