| 摘要 |
This invention provides a reflection-type bandpass filter for ultra-wideband wireless data communication, in which are provided, on the surface of a dielectric substrate, a center conductor and side conductors, provided on both sides of the center conductor, securing a prescribed distance between conductors with non-conducting portions intervening therebetween. The center conductor width or the distances between conductors, or both, are distributed non-uniformly in a length direction of the center conductor.
