低损耗带通滤波器是有线和无线宽带通信必不可少的。但遗憾的是,基于1/2波长耦合谐振器的微带带通滤波器往往要求很大的面积,从而限制了它在便携式和手持装置中的应用。为了克服这一障碍,台湾新化教育大学的研究人员开发了一种取代传统微带带通滤波器的方法。他们采用三角形开? Low-loss band-pass filters are essential for wired and wireless broadband communications. Unfortunately, microstrip bandpass filters based on ½-wavelength coupled resonators often require large areas, limiting their use in portable and handheld devices. In order to overcome this obstacle, researchers at Taiwan's Xinhua University of Education have developed a method to replace the traditional microstrip bandpass filter. Do they use triangles?
