| 摘要 |
This invention relates to a reflection-type bandpass filter (1) for ultra-wideband wireless data communication, comprising a substrate (2) having a dielectric layer (3) and a ground layer (4) deposited on one surface, a center conductor (5) provided on the surface of the substrate on the dielectric layer side, and a side conductor (7) provided on one side of the center conductor securing a prescribed distance between conductors with a non-conducting portion (6) intervening; and the center conductor width or the distance between conductors, or both, are distributed non-uniformly along the center conductor length direction. By means of this invention, a high-performance UWB reflection-type bandpass filter which is not susceptible to external influences and which satisfies FCC specifications can be provided. |
