Claim Text:
1. A method of detecting whether conductive material is present in a thin film, comprising: a. generating a single radio frequency using a transmitter; b. guiding the generated radio frequency signal to a wideband antenna port; c. transmitting the radio frequency signal using the wideband antenna to transmit the signal; d. guiding the radio frequency signal flowing from the wideband antenna to a radio frequency detector; e. converting the radio frequency signal to a viewable signal strength indicator; and f. determining, based on the output from the signal strength indicator, whether the thin film is a conductive thin film, wherein the thin film is in the vicinity of non-conductive dielectric material and wherein the non-conductive dielectric material generates negligible change in the performance of the wideband antenna such that the presence of conductive material can be detected.
