A Wide Stopband Balun Bandpass Filter with Its Application to Balanced Quasi-Yagi Antenna
, 2018 A new microstrip balun bandpass filter (BPF) with wide stopband is presented. It is realized by utilizing the out-of-phase feature of standing-wave distribution on a half-wavelength (λ/2) open-ended microstrip line and the resonant characteristics of the

Balanced Bandpass Filters and Their Applications
, 2010 本論文著重於平衡式帶通濾波器的研製與其應用。首先提出新型對稱四埠平衡式帶通濾波器，以達成所需要的差模帶通頻率響應同時能夠有效抑制共模雜訊。具體而言，適當的設計對稱共振器及善用共模/差模訊號饋入時對稱平面上的虛開路/虛短路條件，可以得到所需要的差模帶通及共模抑制頻率響應。為了驗證此設計概念，特採用三種目前最常被使用的濾波器架構︰集總元件、耦合線、耦合共振器，來研製各種四埠平衡式帶通濾波器。著，藉由適當引入四埠對稱網路至三埠平衡-不平衡巴倫(Balun)轉換器的轉換條件 ...

Advanced Energy Materials, EarlyView.This work clarifies why organic semiconductors perform differently in photovoltaic devices and photocatalytic nanoparticles. By examining D18:Y5 and PM6:Y6 systems, we show how aggregation, exciton lifetime, and interfacial charge transfer behavior govern energy‐conversion pathways.
