Abstract A closed-form method to design microstrip couplers that have tight coupling, practical dimensions, simple structure, and broadband performance is presented. The method is based on the quasi-static even-odd mode approach. According to the proposed method, three-lumped capacitor connected at the center of the coupled structure are used to relax the requirement on the gap width between the coupled lines. The simulated and measured results of 3 dB couplers designed using the proposed method confirm its validity.
