Patent ID: 7307492

Claim:
An apparatus, comprising: a) a first conducting strip having a narrowed width where said first conducting strip also acts as a first electrode for a first tapping capacitance, said first tapping capacitance having a second electrode that is parallel to said first conducting strip; and b) a second conducting strip, said second conducting strip parallel to said first conducting strip, said second conducting strip having a narrowed width where said second conducting strip also acts as a first electrode for a second tapping capacitance, said second tapping capacitance having a second electrode that is: 1) parallel to said second conducting strip and 2) closer to said second conducting strip than said first conducting strip, wherein, said second electrode of said first tapping capacitance is closer to said first conducting strip and wherein a first impedance of said narrowed width regions of said first and second conducting strips approximately matches a second impedance of non narrowed width regions of said first and second conducting strips than said second conducting strip.
