## Abstract A new dual‐band operation scheme is proposed for the branch‐line coupler using two center‐tapped branches. The proposed coupler has two branches with a stub line attached at the center. Only two stubs are required for the dual‐band operation, which reduces the circuit complexity and min

## Abstract This article presents the design and measurement of a microstrip band‐pass filter (BPF) using modified branch‐line coupler with asymmetric open‐circuit stubs in the W‐band frequency range. The fundamental topology consists of using the branch‐line coupler as a filtering section by loadi
## Abstract An extremely reduced size branch‐line coupler operating at dual frequencies of WLAN band 2.45 GHz and 5.8 GHz is presented which is 58% smaller compared to the conventional design. The technique presented introduces the combination method in which the length of series lines is half than
## Abstract This letter presents a novel dual‐band balun using the branch‐line configuration. We establish design equations for dual‐band balun based on the even‐odd mode method. The proposed circuit operates at 2.45 GHz and 5.25 GHz. The single‐ended power is divided differentially at the balanced
