Abstract (en)

The directional coupling device for coupling transmission power in a main transmission line 10 with a coupled line 20. The directional coupling device comprises a coupling transmission line 20. The coupling transmission line 20 is a stripline transmission line comprising a coupling conductive strip 40 supported by a suspended substrate 100. The suspended substrate 100 is arranged between the coupling strip 40 and the main transmission line 10.
