Ultra wideband coupler design for butler matrix application

This paper presents a design of a 3-dB compact ultra wideband (UWB) coupler for a 4×4 Butler Matrix which is operating between 3 and 11 GHz frequency range. The design is using microstrip-slot multilayer technology that allows having a compact and very broad bandwidth coupler. Elliptical shaped stri...
