Claim Text:
1. A printed circuit board comprising: a first signal transmission layer having a first microstrip including a first ground plane; a second signal transmission layers having a second microstrip including a second ground plane; and a via includes a first region having a triangular cross-section, a second region having a triangular cross-section, and a channel connecting said first signal transmission layer to said second signal transmission layer, wherein said first region opposes said second region, wherein said channel is made of a first dielectric material having a first dielectric constant, and said first and second regions are made of a second dielectric material having a second dielectric constant lower than said first dielectric constant, wherein said via allows an AC component of an electromagnetic signal to be transmitted from said first signal transmission layer to said second signal transmission layer while blocking any DC component of said electromagnetic signal.
