Abstract :
A step-impedance transmission line compensation technique applying for parallel-coupled lines has been presented. With the closed-form design equations, the design procedure of the technique is greatly simplified. The simulated and experimental results validate the proposed technique. It is believed that the proposed couplers are suitable for use in many wireless and microwave applications.
