Abstract
The present disclosure relates to a phase shifter assembly comprising a phase shift circuit and a dielectric assembly having at least one dielectric element movable relative to the phase shift circuit for phase shifting, wherein the at least one dielectric element is disposed at a set distance from the phase shift circuit to form a gap between the at least one dielectric element and the phase shift circuit. In addition, the present disclosure also relates to a cavity phase shifter and a base station antenna.
Claims20
A phase shifter assembly, comprising:
- a phase shift circuit configured as printed traces on a printed circuit board and a dielectric assembly having at least one dielectric element movable relative to the phase shift circuit for phase shifting, the at least one dielectric element comprising a first dielectric component and a second dielectric component on opposite sides of the phase shift circuit, wherein the first and second dielectric components abut the printed circuit board such that a first intermediate region of the first dielectric component and a second intermediate region of the second dielectric component are disposed at a set distance from the phase shift circuit to form a gap between the at least one dielectric element and the printed traces of the phase shift circuit,
- wherein a hollow portion for impedance matching is provided in at least one free end region of the at least one dielectric element to expose a part of the phase shift circuit.
