Abstract:
A tunable electromagnetic transmission structure for effecting coupling of electromagnetic signals having a frequency; the apparatus comprising:(a) a dielectric substrate having a first side, and having a second side in opposing relation to said first side; (b) at least one first conductive land carried by said substrate on said first side; said at least one first conductive land occupying a first area on said first side; (c) at least two second conductive lands carried by said substrate on said second side; said at least two conductive lands being separated by at least one substantially linear channel; said at least one channel having a width established by said frequency; said at least two second conductive lands and said at least one channel occupying a second area on said second side; said second area being generally in register with said first area; and (d) a tunable dielectric material at least substantially filling said at least one channel; said tunable dielectric material being electrically coupled with at least two second conductive lands of said at least two second conductive lands.
