Abstract
Disclosed is a bandpass filter comprising a first resonatorto a sixth resonatorhaving lengths of basically ¼ wavelength, an input section IN connected to an ungrounded end of the first resonator, and an output section OUT connected to an ungrounded end of the sixth resonator, wherein the second to fifth resonators-are electromagnetically coupled with each other, the second and the third resonators are respectively coupled to the first resonator via the first and the second capacitances C,Cthe third and the fourth resonators are respectively coupled to the sixth resonator via the third and the fourth capacitances C,Cand the input section IN and output section OUT are coupled to the first resonator and sixth resonator through an input and output capacitances CCrespectively. This bandpass filter can be a small size, low loss filter suitable for UWB (Ultra Wide Band).
