Abstract :
This paper presents a broadside coupler using diagonally shifted coupled lines with adjacent ground through-holes on uncrossed signal line ends. The ground through-holes can generate additional capacitance between signal line and ground which is an effective compensating element for parasitic capacitance around crossed signal lines on an opposite end of the coupled line. The validity of the proposed coupler has been demonstrated by the simulation and measurement results.
