Abstract
A broadband transition between microstrip transmission line and slotline transmission line. The geometry of integrating the two transmission lines results in a broadband microstrip shunt circuit across the slotline, and a broadband slotline open circuit in the direction opposite of propagation on the slotline. This produces direct coupling between the two transmission lines. The transition does not require any intermediate transmission line types between the microstrip and slotline, and no frequency dependent tuning stubs are used to produce the shunt circuits and open circuits required for coupling. The result is a broadband transition which can be fabricated using standard etching techniques and requiring no plated through holes.
