Patent ID: 7242272

Claim:
An apparatus, comprising: a coplanar stripline (CPS) including only a first conductor and a second conductor essentially parallel to each other and oriented substantially along a first direction; and a plurality of essentially linear conductive strips disposed in proximity to the coplanar stripline, the plurality of linear conductive strips being essentially parallel to each other and oriented substantially along a second direction transverse to the first direction, wherein: each of the first and second conductors has a width W along the second direction at a given point along the coplanar stripline; the first and second conductors are separated by a first distance S along the second direction at the given point along the coplanar stripline; the coplanar stripline has a first dimension D along the second direction at the given point along the coplanar stripline, wherein D=2W+S; each conductive strip of the plurality of linear conductive strips has a length l s along the second direction; and the length l s and the first dimension D are approximately equal.
