Abstract
A bandpass filter for a wide frequency band such as UWB is disclosed. The bandpass filter comprises a laminate of a plurality of dielectric layers, a first ground electrode connected to a ground potential, a plurality of resonant electrodes in a first inter-layer and a plurality of coupling electrodes in a second inter-layer. A transmission characteristic of the bandpass filter having flat and low loss over the entire region of the broad pass band can be achieved.
