Abstract

The present invention relates to a T-circuit produced using microstrip technology with two branches (2, 3) of identical length L2 comprising a phase-shifting element (6) producing a given phase shift &PHgr; by extending one of the branches, the T-circuit operating in broadband, the circuit comprises at least one elbow (4) extending the branch (3) without the phase-shifting element and the length L2 is equal to a multiple of &lgr;g/2 where &lgr;g is the guided wavelength.
