Abstract
Apparatus for processing radio frequency, RF, signals, wherein said apparatus comprises at least a first transmission line and a second transmission line, and an electrically conductive element that is capacitively coupled with said first transmission line and said second transmission line and that is translationally movably arranged with respect to at least one of said first transmission line and said second transmission line.
Claims18
An apparatus for processing radio frequency (RF) signals, wherein said apparatus comprises at least a first transmission line and a second transmission line, and an electrically conductive element that is capacitively coupled with said first transmission line and said second transmission line and that is translationally movably arranged with respect to at least one of said first transmission line and said second transmission line, wherein said electrically conductive element comprises at least one impedance transformer extending between the first and second transmission lines, wherein the at least one impedance transformer defines a longitudinal axis, wherein the at least one impedance transformer is implemented in a form of a contour discontinuity of the electrically conductive element, and wherein the contour discontinuity comprises a change in width of the at least one impedance transformer along the longitudinal axis.
A base station comprising at least one antenna and at least one apparatus, wherein the apparatus comprises at least a first transmission line and a second transmission line, and an electrically conductive element that is capacitively coupled with said first transmission line and said second transmission line and that is translationally movably arranged with respect to at least one of said first transmission line and said second transmission line, wherein said electrically conductive element comprises at least one impedance transformer extending between the first and second transmission lines, wherein the at least one impedance transformer defines a longitudinal axis, wherein the at least one impedance transformer is implemented in a form of a contour discontinuity of the electrically conductive element, and wherein the contour discontinuity comprises a change in width of the at least one impedance transformer along the longitudinal axis.
A method of operating an apparatus for processing radio frequency (RF) signals, the method comprising:
- providing the apparatus comprising at least a first transmission line and a second transmission line, and an electrically conductive element that is capacitively coupled with said first transmission line and said second transmission line and that is translationally movably arranged with respect to at least one of said first transmission line and said second transmission line, wherein said electrically conductive element comprises at least one impedance transformer extending between the first and second transmission lines, wherein the at least one impedance transformer defines a longitudinal axis, wherein the at least one impedance transformer is implemented in a form of a contour discontinuity of the electrically conductive element, and wherein the contour discontinuity comprises a change in width of the at least one impedance transformer along the longitudinal axis;
- providing an RF signal as an input signal to said electrically conductive element, and moving said electrically conductive element relative to said at least one of said first transmission line and said second transmission line.
