Abstract
RF transmission lines that include a conductive ground plane, a conductive strip that extends above the ground plane, one or more plastic strips disposed between the conductive ground plane and the conductive strip, the one or more plastic strips having a combined length that is at least half a length of the conductive strip, and a plurality of dielectric fasteners that maintain the conductive strip at a predetermined distance above the conductive ground plane.
Claims25
A radio frequency (“RF”) transmission line, comprising:
- a conductive ground plane;
- a conductive strip above the ground plane;
- one or more plastic strips disposed between the conductive ground plane and the conductive strip, the one or more plastic strips having a combined length that is at least half a length of the conductive strip;
- and
- a plurality of dielectric fasteners that maintain the conductive strip at a predetermined distance above the conductive ground plane.
(canceled)
A radio frequency (“RF”) transmission line, comprising:
- a conductive ground plane;
- a conductive strip that extends above the ground plane, where a length of the conductive strip in a first direction is greater than a width of the conductive strip in a second direction, and wherein the width of the conductive strip in the second direction is greater than a thickness of the conductive strip in a third direction, the first, second and third directions being perpendicular to each other;
- a plastic strip disposed between the conductive ground plane and the conductive strip, the plastic strip having a width in the second direction that is greater than the width of the conductive strip, the plastic strip being separate from the conductive strip,
- wherein the plastic strip is formed of a plastic material having a dielectric constant of at least 2.5 and a dissipation factor at 1 GHz of less than 0.001.
(canceled)
A radio frequency (“RF”) filter, comprising:
- a filter housing having a top opening;
- a filter cover that is dimensioned to cover the top opening;
- a first connector that extends through a first connector opening in the filter housing;
- a second connector that extends through a second connector opening in the filter housing;
- a plurality of resonators within the filter housing;
- an RF transmission line disposed on an RF transmission path that extends from the first connector to the second connector, wherein the RF transmission line comprises:
- a conductive ground plane;
- a conductive strip disposed above the conductive ground plane;
- one or more plastic strips disposed between the conductive ground plane and the conductive strip, the one or more plastic strips having a combined length that is at least half a length of the conductive strip;
- and
- a plurality of dielectric fasteners that maintain the conductive strip at a predetermined distance above the conductive ground plane and that capture the one or more plastic strips between the ground plane and the conductive strip.
