Patent ID: 6943289

Claim:
A planar conductor comprising: a first port; a plurality of second ports; and a conductive planar region electrically coupled between the first port and the second ports, the planar region including a first region adjacent to the first port, a third region adjacent to the second ports, and a second region between the first region and the third region, each region having a corresponding greatest width, the greatest width of the second region being less than each of the greatest widths of the first and third regions, the conductive planar region comprising: a slit located along a first axis and forming an opening from the third region to the third region; and a couple of edge slots in close proximity to the plurality of second ports, each edge slot of the couple of edge slots forming an opening within opposite edges of the conductive planar region and extending within the conductive planar region lateral to at least two of the plurality of plurality of second ports, the couple of edge slots being located along a second axis that is substantially perpendicular to the first axis.
